Feedback and bugs?

Hello. firstful, I wanted to say thank you for creating this amazing game. I've been enjoying it greatly so far.

However, I've noticed few bugs during my play (or maybe i didn't understand some game mechanics).

1) No matter what i tried I was not able to build diplomatic outpost. Even though I have the technology I still lack the option to transform my generic starbase into it. I don't even know if it's separate type of starbases or just upgrade to a cultural one. I can build Culture Ring and Cultural Forum but that's it. No option to upgrade it further. No Diplomatic Outpost, no Interstellar Embassy, no Interstellar Ministry. Tried it on multiple games... Always same problem. And I definitely have required technology.

And while I am on topic. I'd like to know where can I find out how Culture Ring and Cultural Forum starbase actually work. As I understand - it should buff the influence of a planet in zone of control of that starbase(within 5 tiles, if unupgraded). But while building them separate from any planet - they still had some effect. I could see my zone of influence changing around them. So my questions are: Do they generate influence on their own? Does it grow? Or am I wasting resources by doing that? That is unclear to me.

2) One of the most weird and annoying thing was my inability to break alliances. Even though I can see the button to break treaty and on that screen it looks like I did break alliance, the A.I. still counted as my ally. If I mouseover him it even says (++ We are allies, --You break alliance with us!). Problem is - I still can't declare war on him by any means other than proposing resolution to go into war with anyone who defies UP (Which he was doing). Definitely looks like a bug to me.

3) With victories turned off I was not able to continue my game after i researched the last available technology. Game insisted on me choosing something before ending my turn thus blocking my progress. (Only solution I have found so far was to load to a turn before I researched the last technology and setting my focus on researching to zero through "Govern" menu. However that is not a perfect solution as it means I was not able to research everything on my playthrough.)

4) Scoring at the end of the game suprised me a little. Not that it matters to me much but getting score of 6 for achieving Diplomatic victory in a game on Tough difficulty against 7 opponents in 88 turns seems strange. Was playing on small sized galaxy. Again, doesn't matter to me but it seems like something is off.

5) In one of my games I had only 1 opponent left. Yet when I mouseover him in Diplomatic screen it says: you are allied with infidels --, you are trading with our enemies -. Does it mean that I WAS trading and allied with his enemy? Or is it a bug? Wording is confusing.

6) When talking to other nation, option "I would like to speak to you about something." is always greyed out. Is this feature not yet in the game?

7) The only way I know of to see what's A.I.s opinion on other nations is to go intro trade with them and click "Declare war on". It's not really a good way to do it, considering there is a cooldown on trading. Also, if A.I. really doesn't like somebody it says -10 AT WAR, when they are clearly NOT at war. What's up with that?

I think it would make sense to show player how does A.I. feel about other nations when i just click on him once in a Diplomatic overview and then mouseover other nations.

8) Is cooldown of 15 turns on trading with others really needed? It feels really artificial to me. Manipulation with other nations was by far the most effective way to win the game. I get that you should be limited somewhat on your ability to do that, but I am not so sure about that way of doing it. Does it really gets out of control if you allow player to trade with others any time he wants? You are still naturally limited by your wealth and amount of resources and technologies that you can trade. And the most annoying thing is - there are no indicator in Diplomatic screen of whether I can or cannot trade with somebody at the moment. I have to go and talk to everyone of them one by one only to found my trading is still on a cooldown. Very time consuming and inconvenient.

9) Does having negative strategy resources affect ships that using them? Or there are no penalties?

10) I find it strange, that the most research output from a planet you get NOT when you put your focus to 100% research but instead to something like 98-99% and remaining to manufacturing while setting up research project. Difference is really not that big but still...

11) Buying trading cargo ships from A.I. was somewhat confusing. To use them I had to assign a homeworld and the only way to do it was to move them to it first. And then moving them to target A.I. colony. While I guess it make some sense, there was no tooltip on that in the game. Maybe wording is not very clear. I don't really see why can't I "assign" a homeworld to a tradeship while it is in space. Or did I miss something here?

12) Some technologies have grey background in my game. What does it mean? I know that I have them, but why are they grey?(not black like not yet researched tech).

13) Scrolling on menus are really slow for some reason to the point where I feel like I have to just drag the scrolling slider manually.

14) I really miss screen where the game would show me every enemy ships I have encountered in current game sorted by race. You have made incredibly powerful tool in a form of ship designer. But there are no convenient way to see what ships your opponent uses. You have to memorize it all or write it down on paper. Without that information it's kinda hard to know how to build a proper ship to counter your enemy. Seems to me like being a leader of entire nation would grant me advisors capable enough of writing that kind of things for me.

15) Ships window in main game screen is really cluttered. Wouldn't it be much nicer if you had tree-like structure, where fleets would be roots and individual ships in that fleet branches, expandable on demand? Like folders in Windows. Maybe I am wrong, but I don't really see a point in having all my ships on that list at all times. I am creating fleets for a reason after all.

P.S. Thanks for reading! I apologize for my English. It's not my native language.

P.P.S. Edited. Added 5-15.
