I've noticed a tendency for the game to crash when receiving mod-added recipes involving custom items (whether in the ingredients or final product). I've been having crashes while using Faxpax upon receiving the recipes for the Horadic Lutefisk Cube and the Rod of Lordly Might. I'll be posting this in the mod's topic as well, but I thought I should make sure the developers were aware, in case this is a problem with the game engine.
Already fixed for the next patch, it had to do with recipes involving the Lathe, don't hover over the icons, for now.
