I always got this in my console while starting the game.

�[K�[31;1m[09:05:35] [Server thread/ERROR] [FML]: The mod bhc is expecting signature undefined for source baubley-heart-canisters-1.12.2-1.2.1.jar, however there is no signature matching that description

Its nothing to worry about its for fingerprinting Upcraft added it but don't be alarmed

Could this be closed then?

Tbh you should finally set up jar signing @Radient-Sora :p
