In the last few days we sometimes experienced living ZEDs (Cysts, Clots, Stalkers) walking around and attacking us during trader time. It only were 1 or 2 ZEDs so no full spawn and this occured on only 1 wave during a full 10 wave game approximately every 8-10 games. I do not know hot to trigger this. If this issue already has been reported just consider this irrelevant.
