Beta3 .60 Yor tech tree typo and some pedantry

This is the first time I've explored the Kinetic weapon branch, so this might exist on other Civ's tech trees as well:

It should be "Extension" not "Extention".

A perhaps pedantic point: there is no range limit to kinetic weapons in space.  There's no friction, so a slug once fired will go until it hits something, perhaps billions of years from when it is fired, or it might go into orbit around something massive enough to capture it.  I can grok that range could be a key factor in the battle calculations, so perhaps it could be explained as "Increasing the accurate range of kinetic weapons"?
