Hello, so far these crashes have been fixable by the mods using Guidebook adding "after:gbook" as a dependency sorting rule.

See #48 and #51 for previous examples. I don't know which mod you are using that depends on Guidebook, but you might want to check if they have updates, and if not, report this to them.

Thanks for your reply. The only mod i have that uses guidebook is Rockhounding which was just updated. Should i just link this to him in his Git?

Not sure this is same or if this helps.
Client crash when using guidebook. If mod is removed the modpack works fine.
Happens more frequently with linux and MAC clients than with Windows clients.

No that doesn't feel like the same crash, since this one is with ItemRegistered, which sounds like the embedded utility library wasn't properly extracted and loaded into the memory_repo folder (mods folder in older versions of forge)...

It's been happening for some clients, but the majority are working fine.
We haven't been able to find the common issues those specific clients might be having.

So is it a "fix" on your side that can be done?

Thanks for your hard work and quick response.

I can't think of anything I can do myself. I just declare that I have an embedded library, forge takes care of extracting it :/
