Was curious if anyone else has seen this bug as it scared me last night, i was rearranging my master tool-belt because i wanted to use my pick and pan and moving my shovel into a box. so i had the window for inventory/belt/box up and pick and shovel in a box, farmers hoe in my hand for some reason and a full belt of tools. i picked up the pickaxe and then shift clicked and the pick vanished, didn't drop or anything just vanished i got worried and ran around searching so i went to the box again and shift clicked the shovel it too vanished and was no where to be seen.
After a few minutes checking backpack, belt, inventory, ground etc i used the mouse wheel to roll out my belt to empty it and presto my tools appeared.For some reason they went into my tool-belt directly from the box into a void space. i was unable to reproduce this and am curious if anyone else has experienced this.
