Found and fixed, thanks for the report. The reason this happens is that there are none of the item being crafted in your inventory. The reason that Scorpius, Lacertium and Leporine works is that you are already carrying at least one of those. Scheduling this for a bugfix release, but I'll to see if more bugs are reported before releasing.
If you want to get around it in the meantime, you can either buy/pick up a drop one of said items, or use the debug ITEM cheat in the nomad tent.
