The "custom" creatures in toolset are still there, but in the DM creator they are missing. The only thing in the custom creatures DM Creator is "Merchants" and "Special". The custom creatures still spawn on encounter in-game, but we cannot create them as a DM. We've also attempted to roll back the server, but the issue persists. If anyone has run into a similar issue, any advice on this matter would be helpful. Thank you.

Hit resource limit. Fixed by cutting a couple of scripts.
