The autogun, when die, can drop over 100 circuits, Exterminators, etc.
This should really be prevented. Us could create a separate class for the
autogun that don't drop any item, or add a filter at the function that make the
itens be dropped randomly, so, if the bot ID is "GUN", skip the dropping
sequence. The worst problem, in my opinion, would be retrieve the bot type, to
compare if it is a GUN robot. The rest is pretty easy.
