Well, I don't know, but here is a personal theory.
The game was released a few months ago. Now, after the end of the elections in the USA (the main market for this game I presume), and months after the first release, the game is probably not going to sell many more copies for UBisoft. So, they might be thinking, "why spend money on QA for a 'dead' game, we already have the money of those who would buy the game", so they just let it slip. Same thing happens IMO with many other companies and games. Another example is what happened with Starfleet Command III. Where IIRC there was never an officialy released patch from the publisher, since they released the game too early to be released near the Star Trek Nemesis movie, and after months they were probably thinking, "what is the point of wasting money on fixing it? since as they were seeing it whoever was going to buy the game already did. I am not saying they were right, or that this is what happened, just my personal theory.
