As title, I've just realised that at some point in the near past the game stopped allowing me to pick items up. Well, I can "pick it up" but everything I pick up just dissapears into the void never to be seen again and doesn't get added to my inventory. Even items added from the console don't appear in my inventory, help!

After some investigation this seems to be save-game specific, if I go back to an earlier save it resovles itself. But seeing as my last non quicksave was about 5 hours ago (I know I know) I really don't wanna do that.

Based on your other threads, If you have hosed your save with mods, then there is not much to do but load up that earlier save and go on.

Always have a test save, preferably made with no mods at all, to test your mod mixes with. Never save over this slot. Once your mods are tested good, then load up the save you want to play on with. Even then, fork that save.
