Posted September 1, 201213 yr So I'm working on a mod called zoocraftia and in transition from forge 4.0.0.217 to forge 4.0.0.243 I got this error after first launch on forge 243 without any changes made, the same error repeated until I remove the @Instance annotation from my main instance(of course I got NPE after that).

October 14, 201212 yr Could you tell my how I think I have the same problem (even made a topic about it) I try not to be mean about your english (as my own isn't the best either) but sometimes I can't help myself! If you get mad at me for this or any other reason, please look at the profile picture so you'll feel better (and pretier) than me! Thanks.
