Fatal Bug: Item Editor Broken (635)

Whenever I choose any item with unused attributes, weapons, and flags and click out of it to choose another item, whatever was non-editable with the previous item becomes permanently non-editable with all the other items that you select in the item editor, and the worst part is that it disables editing of misc properties, misc flags, and weapons used for the items mentioned in the thread about the item editor misc attributes.😞
