Why were trolls and rangers turned off again?

Just curious why session play was disable in the Moors again? Trolls gave creeps a means to fight the insane number of freeps running around now. I guess it's better to wait and see what happens to the map before I start calling for gloom and doom. I just wanted to know why they were turned off. The wink lead me to think it's because people were complaining again.

I'm looking into this one. I have no idea why they were disabled.

An exploit was discovered that enabled sessions to be nearly limitless. It was decided that the sessions should be shut down.
