I'm playing Steampunk [LPS] mod pack and it has your 'spyglass_improvements-1.5+mc1.19+forge.jar' in it, when we put in 'controllable-0.18.0-1.19.2.jar' in it for controller support, it locks up at booting.

Log file shows:
[01:50:21] [main/WARN]: @reDIrect conflict. Skipping controllable.mixins.json:client.MinecraftMixin->@reDIrect::onKeyDown(Lnet/minecraft/client/KeyMapping;)Z with priority 1000, already redirected by spyglass_improvements.mixins.json:MinecraftMixin->@reDIrect::handleInput(Lnet/minecraft/client/KeyMapping;)Z with priority 1000

seams both mods are fighting for Z key. I notified controllable and modpack people also on conflict. Just figure I'd let you know also of this conflict :D
