 +:!: //Redirectors of all kinds work by redirecting the target to your handler method. This causes a hard incompatibility if another mod tries to redirect the same target as this makes it impossible to chain or nest redirects. This makes @WrapOperation and @ModifyExpressionValue from MixinExtras preferable for all use-cases where the developer does not directly intend for an incompatibility. You can find more information about those alternatives on the [[https://github.com/LlamaLad7/MixinExtras/wiki|Official MixinExtras Wiki]].//
