In my shop I right clicked an item to get into the second menu to toggle whether to sell the item, change item price etc. and accidentally clicked my Comet 290. It entered the menu so was not stocked as a new item to sell, and I couldn’t get it back out. It disappeared when I closed and reopened the menu.
Request for Solution
Return the Comet 290 please
