Dump an error while starting server.

I'm testing this on my own, and I have only been able to reproduce the issue when UBM is installed. Just because UBM is not mentioned in the stacktrace does not mean it is not responsible. I'm going to add UBM to my dev env and see if I can identify the issue. It may be a race condition.

Even though this bug only occur when I try to enable Universal Bonemeal @Fuzss ?
Most likely mods incompatibility.

I don't think this has anything to do with Universal Bone Meal as it does not contain anything related to this error and is mentioned nowhere in the stack trace.

It's probably just a coincidence that you installed the mod at the same time the crash in Ecologics occured.

The only thing in my mod I can think of this could be related to is data pack reloading. I hook into that to recompile a block list based on tags.

But apart from that my mod doesn’t really touch any other areas of the game, no mixins or whatsoever. Only a single event is used for all the bone meal behaviours.

@Fuzss added the logs files

Loot modifiers are handled within the datapack, so that definitely seems like a possibility.

You should report this to the Ecologics mod instead.

@Preciel I release a new version (v3.0.3), can you do a bit of testing if the issue is resolved please?
I'm having trouble replicating the issue both of you got.

@Fuzss just tried and no error occured. ;)

Great, thanks for testing!
