I would like to second this mod, with some recipe changes, (helm requiring steel and air balloon requiring helium, for example) and with the rule to NOT use any mod tile entities on a ship. Chests only.
EDIT: By the way, if you guys like UHC, what about Iguana Tweaks and/or Hunger Overhaul?
I wouldn't mind the airship mod, depending on how much lag it'll cause.
Iguana tweaks i'd say maybe, same with HO. I don't really care either way.
Custom ore gen is updated, we just need to wait for PFAA. No commits yet, but I'm hoping soon
