when your beloved husband, who is learning French on Duolingo, wishes that he could practice it instead of spending his time playing Skyrim. I suggested that he switch the language option to French & play Skyrim in French. Well, he couldn't figure out how to do that for the main game, but there is a French language option in the DLC. So I deleted the English DLC & installed the French DLC.
He turned on the game, which he had saved just after arriving at Skuldafn. Deleting the English language DLC also deleted everything associated with the DLC, including his Carved Nordic Boots with dual frost & fire protection, his Stalhrim sword with 68 points of frost on it, and his favorite conjuring spells.
He's running around Skuldafn with bare feet.
Oops.
I'm sure that his (only) house, located in Raven Rock, is gone as well, along with everything in it: loads of weapons, smithing materials, a huge store of alchemy ingredients, and tons of filled soul gems.
My name is Mud.
