Since I'm not as familiar with the modding scene for stellaris as I am with say, DF or Cata DDA, what kinds of mods would typically still work unmodified after an update like this? I imagine anything that changes game values, like expanded ethics are out, but would things like Avali(cuddly space raptors yay!), flag icons, and coloration stuff still work correctly?
Well, I know the species mods broke after one update or another changed the way that species groups were organized. Some of them still haven't been updated and are useless now.
So I wouldn't assume that any mods will remain unbroken after Banks is released.
