Using Splitting Gambit with a number greater than (2^31)-1 mishaps, and running a Craft that would produce more than that number clamps the value. May well be other cases that I haven't seen.

(I think you already know about the Splitting Gambit one, but I don't know of any prior discussion of the Craft one, and there wasn't a github issue for this yet)

alright, should be fixed for the next release; also fixed the possibility of OpCraftMote doing a long overflow

Correction: I think I misinterpreted a wisp running out of media in the middle of a crafting hex (and leaving maxint of something in my nexus) as the output clamping issue in the original post
But the splitting gambit mishap is definitely a thing
