Dinos disappearing in singleplayer after loading a save

I’m talking about the single-player. It works fine on my dedicated server, but single player somehow loses the Boas after a reload. I can spawn the Boa in single-player and then exit and load my save and the Boa will be gone.

Could it be that the single-player isn’t loading the Boa file correctly as the blueprint shares the same name as the vanilla Boa (I know stupid, but I was a real newb when I made the mod). I’m now trying to change all the names of my files to make sure they are in order and don’t have a chance to conflict with vanilla files.

The bad thing is that the upcoming change will also wipe every modded Boa even on servers. Then again I should do it now perfectly to ensure future compatibility. I hope not everyone will hate me for their lost Boas ;_;
