[SOLVED]FML @Instance error

[battlefield]

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).
