@ springerjkreb: Both are issues with the DEFAULT USM .dlg files. Which means you didn't properly install the files from the Compatibility patch. And we made more severe fixes than a few mere convo breaks (whoever did the .dlg editing in the USM doesn't seem to had any idea what he was doing, at least to me).
@ Acleacius: Yeah, not all clothing models work (I believe several are NPC, not meant for the player to ever get). Though you shouldn't get them with "just" TSLRCM.
