Hey, using the latest 1.12 Forge and had everything working great. Then on the latest system maintenance, the server wouldn't start up again, and it appears to have something to do with animania and cheese molds, or maybe milk? Here's the crash report

Is this a first time launch, or did this somehow get corrupted later? Can you give me some context?
Oh wait, saw your note at the top. Could be another AppleCore issue. What mods did you update besides animania ?

Updating to the latest version fixed it in future worlds....

@capnkirok Last update was June with the message that it's fixed? I think you need some closure 😅.
