Hey Barrelmaker, thank you for the detailed bug report and fix suggestion. I've implemented your fix in this 1.1.3 update. Let me know if it continues to give you trouble, and if it does I'll try to carve out some time to look into it further. It's weird, because A) it's not crashing on my machine, and B) there's an entry in the changelog from Ruigi from 2012 fixing exactly the problem you list.

In case this doesn't get fixed, to any future readers, here's the quickfix I made for myself:
1. Go to your Documents\Gaslamp Games\Dungeons of Dredmor\steam_workshop\subscribed directory
2. Unzip 3348516952-1728876429 (this mod)
3. Go to the skills folder and copy out the three pairs of Imperial Officer art files from there. One should be IObicorne, one should be IOsilks, and one should be IOsaber, and in each pair, one 32 and one 64.
4. Rename each copy to the lowercase: for example, iobicorne64.png, iosaber32.png, etc.
5. Put these new renamed ones in your Dungeons of Dredmor\skills folder, wherever it is installed. No more missing art files.

It would appear these item-related buffs are case-sensitive. Please coordinate either the files or the reference in spellDB.xml to IOsilks or iosilks
