Hi, this isn't us. If you isolate BnC in an instance, it will not do this.

That line is simply logic to make sure a part of a loot condition (for the Keg temperature advancement) works.

Could you potentially binary search to find who it actually is and report to them?

The binary search is a way of finding a faulty thing among a lot of other things, without having to remove the things one-by-one.

This is useful for finding a broken mod among hundreds of mods, without having to spend time testing the mods one-by-one.

The procedure is simple:

1. Remove half of the existing things, and put them aside.
2. Run the program / game.
3. Does the issue still exist?
   • If YES: Repeat from step 1 with the current things.
   • IF NO: Swap out the current things with the ones set aside, and repeat from step 1.
4. Repeat this process until the problematic thing/s have been found.

OK,I will try it tomorrow.
