I was getting along fine until trying to save. I would get errors. When scrolling through the entire list of items, I noticed that there was an item call "Air" that would pop errors just by highlighting it. I cannot change it to something else unless I change my entire inventory to another item (i.e. Set All to Currently Selected) because it pops up with an error "System.ArgumentException: DataGridViewComboBoxCell value is not valid." I have searched through all my chests and have no items that even have the same quantity as the "Air" item. In the editor, as soon as that item is highlighted, it starts popping the error message above. If I actually click on the item (instead of the id or quantity), I have to go to the Task Manager to end the program because it gets caught in a never ending loop of the error above. Is there any way to remove the Air item other than replacing all items in my inventories with the Set All option? Copy of save .bin here: http://www.mediafire.com/?02gzlcrg1wjyx9w Thanks in advance.
