Tweaks
Mod category: Tweaks
Small changes concerning balance, gameplay, or graphics.
If you are using ERM I think you need to disable RSO biter spawning and switch to vanilla. Otherwise it might not function properly.
There are 2 options: startup one to enable vanilla spawning and map option to disable RSO enemy spawning.
I think I might need to add general warning somewhere that various enemy editing mods are not fully compatible with RSO.
