2 or 3 tiles south & 2 or 3 tiles west of the mega dwarf's "entrance" there is an arch dwarf that will not stop spawning; kill him & he respawns immediately. I have seen this bug in other places like lab6 when a skelly steps off his spot to attack, another replaces him. But there it happens once & you just kill them both, no big deal. This one is not just 2 mobs, it is pretty much an eternal fountain of dwarves. I hosted my own killfest there tonight. If I had some pack space & wanted to abuse the lag scroll I could have had infinite titanium axes....
I would probably die if my spells ran, but I bet a templar could just afk himself to warlord there.
