Ideas
I recently got an error code with the help of MCCC and Better Exceptions that didn't really explain what the problem was except for the reason which had the word "Digital Photo Frame" in it. And I'm a person, like many others, who loves taking pictures of the families through generations. So I got concerned for if a photo had disappeared or anything, checked the walls, the shelves, they were all there. UNTIL.
I remembered I have one of those Modern Photo Frames from the event (which is the only new variable cause I had never gotten an error like this before, even with my mods). I tried to drag the picture out of the frame, didn't work. Selected it, "oh it has an inventory"... it's empty... "turn off? oh it turned black" went to check the inventory again. Still empty... "ok can I turn it on?" 'Requires at least one photo in the photo inventory' "you have GOT to be kidding me."
Quit the game without saving, placed all the mods in another folder, restarted the game. The picture is still gone from the inventory. Tried putting it in the household inventory (the photo still shows up on the icon in the inventory so I was hopeful) put it back onto the counter, still no photo in the inventory.
So now my, actually very beloved, picture is gone. Not in anyone's inventory, not in the household inventory. Not on the ground, not on the wall, not in the frame. :I PLEAAAAASE fix this so it doesn't happen again!!!
