When I enabled brewing on my new build of 1.17.1 PurPur with my old 1.12.2 Brewing files, when it trys to do something with chunks, I get this nasty hangup each time I boot the server, as soon as I remove Brewing it stops, im going to assume this is something to do with my old data set? And im assuming barrels if its chunk loading?

I temp removed the worlddata.yml to see if it was the thousands of brews people have made, but same issue.

Barrels are also stored in the worlddata, so it cant be them loading the chunks.
It could also not be Cauldrons, as they are also stored in worlddata, so i really don't know what could be causing this.
