Getting errors like this for every group I have, instances don't load in, and when I do build something, press save, and reopen the game they don't load in.
[LOG 10:30:17.152] KK: [GroupCenter] SetInstancesEnabled: Setting Group KSC_Builtin: active state form: True to: False
[LOG 10:30:17.152] KK: [GroupCenter] SetInstancesEnabled: Setting Group CapeCanaveral: active state form: True to: False
Edit: for some reason, KSCextended was messing with it. Not sure how.
