Actually I might have just found the conflict, I got forward to work now and heavily suspect the CharacterLeanVariable action to be the conflict. By default they show up as Q and E but they also don't seem to work by default, although that might be because CharacterLean is bound to the same key and just override the partial behavior. In any case, this is promising, but calls into question what the keybind UI should do when players bind keys to actions that block other actions.. hm, tricky. The least that is needed is for players to be able to clear default or custom bindings, so they can remove the partial lean keys.
