AECapFix
Fixes AE2 capabilities by adding proper invalidation.
About this Mod
A relatively small Mixin-based patch mod that allows Forge capabilities in Applied Energistics 2 and Powah! to properly invalidate themselves at the end of their life cycle. This fixes interactions between AE2 and certain mods which refuse to listen to neighbour updates as a contingency measure.
