Modpack Version

1.15.2

Describe your issue.

When trying to use tansmutation in the theurgy mod, everything works fine for about 5 seconds when the process starts. I was converting Precious Gem niter into Precious Metal niter. Then all of a sudden I'm kicked from the server. At the moment, I'm both running the server and the only one in it, so I don't know if it's just me, or it would kick everyone. The process stops while I'm not in the server, so i rejoin, it carries on for another 5 seconds, then kicks me again. I could just keep rejoining repeatedly until it was finished, but I thought it safer to just quickly remove the niter to stop the process.

Side note, you can't shift click the fermentation barrels to close them with a shield in your offhand. If you put the shield away it works fine. Same for the chopping board from one of the food mods. It just puts your shield onto the chopping board instead of what's in your main hand.
(Sorry for the rant)

to make troubleshooting easier:
join the server, prep and start the process, let it kick you
close the client and re-open it (to clear latest.log and generate a new one)
join and wait until it kicks you again
close the client and post the latest.log file from the logs folder
