When applying the tables for crafting items (tanning, bench, cauldron, etc.), items can be made while the player has the table open. Should making the item fail, however, and in some way cause the table to be destroyed (via fire, uncontrolled mana, etc.), it causes the player's inventory to treat the table as open but non-existent when using keyboard/mouse command short-cuts to pickup/drop items.
For example, I tried using comma to pick up iron bars after one of these instances and got this message: "04:38 There is nothing in the container to move". Right-clicking to drop items also stops working after destroying an open table.
