With the latest Beta update, players have noticed additional delay when aborting Recurring Quests (approx. +1.5 seconds per one). It was at first considered as a bug by players, but then we had an official word from FoE personnel that delay was added to, I quote, "prevent exploiting of the recurring questline".
This also means significant nerf to CF too, as you will be able to do significantly less RQs than before per specific timestamp.
