When running the most recent release of both CraftTweaker and CookingForBlockheads, CFB causes CT to crash out and shut down the server.

When I disabled CFB, my server starts up with no issue.

Please see this issue ticket as well for additional information https://github.com/jaredlll08/CraftTweaker/issues/170

Looks like the problem lies with a furnace recipe that results in nothing. Cooking for Blockheads doesn't error-check in that case yet.

Specifically it seems to be some Refined Storage furnace recipes in your scripts (see minetweaker.log):
