What? That happens often, especially when your in town sometimes. If you tick the option [x]stop botting when GM spawns near to you, bot just stops.
If you tick the option [x]disconnect when GM spawns near to you (only while your botting is second option) then you dc. That happens sometimes...
But thats not new that theres GMs at any spot. At new servers they are also in the beginner training area... ;P
