Rod of the Python shows up in the Info panel under Inventory -> Equipment with its to-hit and damage bonus, and I see those properties in the Rod (Python) entry in the .lst data file, but when I equip the item and look at the character sheet tab, the +1 bonus to damage is not present (it's just 1d6). Screenshots attached.
The item also has no real description, but that's much less of a problem than the bonuses not being counted.

Apologies, I'm an idiot – you may delete this ticket. I wasn't thinking about my STR penalty to damage, and it isn't listed on the troubleshooting character sheet view (maybe that actually deserves fixing, but that's a feature request).
