Thought I should check the change logs and my mod versions. My save has exotic-industries 0.4.1 (I started this play through around a year ago). I don't see this issue being noted as fixed anywhere, but I also see a lot of recipe changes that make me nervous to update this late in the playthough. On the other hand, I don't see anyone else reporting this issue, so maybe somewhere along the way it was fixed. And I'm realizing now, as I make and typo-fix this second post, that this is probably misplaced, and should probably be under the normal (non-modpack) mod.
