Hi guys, May of solved is this time, I'm pretty sure it was to do with the "drag and drop" feature I added in a previous patch. I also limited the amount of an item the game calculates to improve performance if you tend to have a lot of items in your inventory. Here's the full patch notes: [list] [*] Added crafting limit to 32 items at once. [*] Removed inventory "drag and drop" feature. [/list]
