I can't seem to find the tab to craft the Houndious Shootius

Well I can't speak for the other mods you refer to, but this one was created specifially for my servers.
As such, it customized exactly the things that the players on the servers wanted customized and nothing more, thats why it may seem random ;D
Also this was when caves weren't released and the game was still in early access.
I assume a lot of the stuff is obsolet now.

Haha lol

Xd

Pretty random options I would say ;_; Ugh... What I don't get is why there's so many little mods that do a lot of the same/similar things. Would be great if some day, someone would make one huge mod with a whole bunch of options of the existing stuff in the game, editable at your disposal. And perhaps some of the stuff in some existing mods too. Idk. Just wanted to throw this out there...

XD
