I know its only been about a year since the last reset, but I was wondering if it might happen when 1.9 becomes stable. I don't know, but that would seem like a good time. Anyone else agree or hope its time for one?
There's been no set date for a reset to my knowledge. But if it was my opinion, I would guess it would be late 2016 and, at the most, early 2017 that Prison will reset.
All the information on this topic that is known to me, is that it's getting reset after factions, which already reseted. I would expect it to reset maybe during the summer or after that.
