This happens every time someone right-clicks the Cooking Table.

The server is running the FTB Revelation modpack 2.6.0-1.12.2 with CookingForBlockheads 1.12.2-6.4.65.

Same for me
Server crash when I try to use the Cooking Table

Ok, found why
Because of that:
# Enabling this will make the kitchen counters have twice as much inventory space. B:"Large Counters"=true

If you have charged this value middle game, cabinet can have different size, and make the game crash!
Can also appen if the config betweeen the client and the server differ

This was fixed a while back, must have forgotten to close.
