Hey there,
I'm the creator of LittleTiles and apparently there is an issue with Controllable in 1.12.2.
LittleTiles adds an event call in Minecraft.sendClickBlockToController() and it looks like Controlable has a problem with that.

[04:51:36] [main/INFO]: [org.spongepowered.asm.mixin.transformer.MixinProcessor:applyMixins:362]: org.spongepowered.asm.mixin.injection.throwables.InjectionError: Critical injection failure: Argument modifier method sendClickBlockToController(Z)Z in controllable.mixins.json:client.MinecraftMixin failed injection check, (0/1) succeeded. Scanned 1 target(s). Using refmap controllable.refmap.json

Not sure, why your injection expects this method to return a boolean? To be honest I have no clue how to fix it, but maybe you have an idea.

sendClickBlockToController(Z)Z is actually the signature of my Mixin method, not sendClickBlockToController(Z)V from Minecraft class. Unfortuantely my Mixin can't find the targeted method since it's being redirected/overriden in your mod.

Oh right can your mixin maybe also accept my redirected method call (in theory that should not make a difference)?

It's possible but I am more likely to discontinue the 1.12.2 version of this mod. It's just too time consuming to maintain.

is that an option? Otherwise we can also find a different solution.

Can relate, thanks for the answer!
