Perhaps compatibility with Renai Transportation?
And I'll be honest the Renai compatibility is just because if we're getting silly with fish we might as well get really silly.
Overall I really love this mod, the randomization of the recipes has given me quite a bit of fun with puzzling out the solutions, without the kind of progression grinding that the huge overhauls have with their new weird recipes.
I can't wait to see how much more convoluted fish can become.
