Geothermite's loot table didn't work

in cave_vent_mite.lua line 62    if Geothermite drop loot in shielded, It have a 100% chance of dropping a rock.

However, when Geothermite dies, it will exit the shield state and enter the death state. This will set the "shielded" parameter to false. So this 100% chance will never be triggered.
