I'm having an issue where when I load into the prefab editor, my toolbelt is locked. I cannot drag anything to/from it. If I want to add something from the creative menu, I have to first add it to my backpack and then shift + left-click it onto the toolbelt. However, once it is there, I can't remove it either by dragging it off or selecting it and pressing "D" while it is selected either. So when the belt is full and I need to add new items, I can only click the trash can in the backpack to clear my entire inventory to clear the belt. Then I have to refind/add all my static tools, like the dig gun, paint brush, etc. It seems I simply cannot click the toolbelt. If I click on an item on the belt, it does not select the item at all. But if I use my scroll wheel, I can scroll through the toolbelt to get to different tools. This is a real slow down. Anyone had this issue? Is there a way to unlock the toolbelt?
