I had a problem with some of angel's refining recipes (when mad clown used) which had 9 resulting items. The generated description had too many localised string and was crashing on startup. The game claims that 20(?) is the maximum and the limit was being exceeded. I fixed it by limiting the description generation to omit recipes with >=9 resulting items. It's hacky but may help some people.

That's interesting. Looks like this limit wasn't a thing when I did my last playthrough with MadClown's mods.
I'm already addressing this issue in next update, but can you tell me which MC recipe caused a problem?
