So this isnt an issue ive heard of before. Just to be sure this isnt an easily solvable issue, try this. Next time youre in game, use the command /isearch ______ and where the blank is, put one of the words in the name of the item. That should give you a list of every item you own that includes that word(so if for instance i misplaced some Moonshine Twine i could use "/isearch moon" and get a list that would include the twine and any other items i have with the word "moon" in the name). Then find this particular item on the list, and using the contextual menu(right click if you use K/M) pick the "Search For Item" option. This will give you a list of where every copy of that item you own is, including the page of the inventory, along with just a general count of how many total there were. Hopefully this helps.
