My mods are as followed, Biometex colonies CreativeMode FCSMod StarMount Creative and FCS worked fine for me in the past, and just earlier i installed the other 3, when i get this (attached as a screenshot What happened? Do I have to remove a specific mod?
Just means that a mod in there has their own variant of the same monster with the same name. You can try adding them in 1 by 1 and seeing the source of the issue. You can cross my own mod off the list, as I dont add anything other than NPCs.
It wasn't colonies, I removed them one by one and found out it was StarMount with the issue, thanks for helping
