GM flag vs status?
 

Is there any reason why the agro check code checks both the gm flag and the account status flag?

This means that if your account is flagged to allow you be a gm then you can't have normal agro for testing and so on. It seems to make more sense to me to just check the gm flag so that you can turn on agro by doing #gm on and off again by doing #gm off

Does anyone know why it works the way it does?

So Quest troupes don't get attacked and swarmed with NPC's

Ah, that makes sense although it would be nice if there was a seperate way to control agro for testing.
