I'll see what I can do: I'll need to verify the original ZQ version in which EoTDX was created, and patch the hammer's hitbox for quests with that build signature. For the present, I am only going to modify the hammer hitbox if a quest has that specific build ID, for fear of breaking it, elsewhere...
@Saffith fixed the hammer hitbox to the left, I believe, but not upward. I'll need to see if that commit was llost somehow, too.
