On multiple occasions the inventory has jumped back to an earlier state whenever I try to drop items. It shows that items I have already dropped are still in the drop list and my inventory doesn't match what I currently have. And if I try to drop the stuff again, it resets my inventory back to what it remembers from ages ago. Any new items get deleted and old items I've used or sold reappear. The only time I fixed this problem is when I saved the game as a file and cleared the entire cache of the browser and reloaded the file. Inventory worked fine after that and would break again after a couple days IRL.
