A really odd thing happened. I had installed a couple new mods (http://skyrim.nexusmods.com/mods/9247 and http://skyrim.nexusmods.com/mods/26494) and loaded up a save game. I played for a little while, then had second thoughts about where I was going, so without quitting to desktop, I reloaded the same save from the beginning of my play session. Upon reload, my character was missing two items (rings from http://skyrim.nexusmods.com/mods/19833) and her stack of 12 clam meat had changed to 3 raw rabbit legs. I shut down the game and checked on NMM, apparently two .esps from Dual Wield Parrying were active ( I could swear only one was when I installed it but whatever), so I deactivated one, and moved Hotkey Your Gear further down in the load order, just for kicks. I then reloaded that same save and the items were restored. A few hours later, after having a hair-pulling hour trying to figure out http://www.gamesas.com/topic/1421990-game-crashes-when-you-save-during-quest-waking-nightmare/, I realized that another one of my rings went missing (and who knows what else, that's just the thing I noticed). Since I am not planning on reliving that Waking Nightmare, I will just live without it I guess. What on earth could cause something like this, especially when the clam meat transformed into rabbit leg? I think I need to learn how to use TES5Edit...
