I found a small bug that I'd like to report.
It occurs aboard the Ebon Hawk, when sparring with the Handmaiden. When she gets rid of the clothing she's wearing while you talk, the clothing does not return to the inventory, instead, it just disappears. I have not checked to see if more valuable form of armour disappear the same way, but I will if requested.
I am using the 4-disk version of TSL with RCM 1.7 and 1.7 Fix, along with the Enhanced Merchants Mod.
