Fixing My BeaconBlockEntity Mixin

[RacoonDog]

I made a basic mixin of BeaconBlockEntity that overwrites the tick method with an exact replica of the vanilla code (as far as I know), yet it seems to break stuff and make the beacon active even though it shouldn't be. I've tried my best and am unable to figure out why or how to fix it. I've got four important classes: the mixin, 2 accessors/invokers, and a util class.
