I checked all the .utc files you listed, and the only one without a .mor file is arl210cr_jowan_corpse.utc, but when I set it as hm_bhm100_jowan.mor and started a new game, his head is still missing, so I doubt this is the problem. You can open the files with DA Toolset. Removing the IA folder from override fixes the problem, so it is definitely something with IA. EDIT: I found the problem: Within IA, there are two different bhm100cr_jowan.utc files: one in 2. Modules\2.2. Characters, where I checked the files, and one in 3. PC Origins\Mage. The second one is the one at fault since it is loaded last. In it, the name of the .mor file is hm_bhm100_jowan2 instead of hm_bhm100_jowan. SpaceAlex, the author of IA, actually posted a fixpack for this on the 7th, it just didn't occur to me to look at the posts for an extra update patch (I thought it would already be released with the main file). So there you go, problem solved, have fun playing ^^
