I have inventory contents turned on so when I mouse over a bag it shows a window and a list of all items in the bag. I noticed that items I was looting were not visible in any of my bags. I moused over the main inventory bag and noticed the list was HUGE and items I looted a week ago but were not visible in any og my bags were listed. I started moving things around and found a spot on my main inventory that after I moved my deconstructing hammer from that spot I could not add a abomination body part to theat spot, it would say wrong type of container. I cleared out a second spot on my main bag and if i moved the hammer to the new empty spot anf then back to where it was a missing item appeared in the slot where the hammer was. I did this alot and seem to have cleared out all the hidden items but it was like 50 items worth of stuff.
