Having the same issue with the Thread for Sage gear on our server. Also 1.12.2/4.3.3

Do either of you have CompatSkills installed? The current version was causing problems with the arcane workbench.
Edit: may be related to #608, the above info would still be useful though

Assuming this is the same as #608, now fixed in 4.3.4. Please reopen this issue if you still experience this problem.
