New build! https://wiki.arcengames.com/index.php?title=AI_War_2:Finalizing_Multiplayer#3.006_Rising_Spire
(Reminder that if you have trouble with the build, you can always go into betas and choose most_recent_stable to go one build back. This is how I sleep at night after making some major changes.)
This one properly fixes OSX OpenGL support. Sorry that didn't quite work correctly on the Saturday build, but it should now.
This one also sees some major balance adjustments (buffs to the player) for DLC1's Fallen Spire campaign. As the game has continued to evolve, that has remained a popular way to play, but those ships under your command were starting to feel rather on the underpowered side. I believe it was Badger whose play group noticed that during a MP session over the weekend, and so ArnaudB went through and made a ton of adjustments to make that more in line with what they once felt like (sometimes this is a bit of an arms race with ourselves).
At any rate, Combat Factories in the base game also got a buff to the strength of their drones, AI Golems in the base game and DLC2 both got buffs, and there have been a lot of improvements and fixes to Outguard. Thanks to ArnaudB, CRCGamer, and StarKelp for those things, along with a few other fixes and tweaks.
More to come soon!
