Vaal temple - workbench bug.

When upgrading my Sceptre, it upgraded as expected, but is dropped on the floor, along with support gems.

In one instance, one of the two support gems disappeared completely.

I believe, that if the gear item is taken from hand, it should be replaced back in my hand, not thrown on the floor. Or if it was in my inventory, it should be placed back in my inventory.

Thanks.
