A few things I noticed in the 2.6 opt in preview;
Technology capital consumes 1 or 2 arnor spice per turn once built. It's also listed as +1 arnor spice when you build as opposed to other buildings that say -1 to build. Right now its completely messed up and will eat all ur spice!
In the tech tree for beam weapons; lots of the specializations descriptions still say "increase beam damage" when the tooltip icon correctly states and increase in range. Also in the tech tree is a support module that "increases beam damage of the whole fleet" but actually only increases the damage of non-elerium beam components.
In the battle viewer, i will still (i think someone brought this up before) see my support ships way out in front but not interacting with the battle. It doesn't change anything, since they aren't supposed to do something, but looks dumb as hell.
The computer never seems to want to attack my privateers, so i can fly in and wreck all their starbases and peace out with 0 consequences. Do they not see them as pirates or something?
Surrendering AI will still sometimes bug out and have ships in orbit of planets they no longer control.
Thanks, that's all I remember for now!
