So far I have found two new events in Kessex Hills outside of the killing the flowers that spawn.
One is located to the east of Ireko Tradecamp Waypoint when there is lighting in the sky involves closing 3 portals [Clear Toxic Alliance forces from Eukaryan Caves.
The second starts of as an escort quest right to the west of Overlords Waypoint involves escorting some liongaurd to Mudbay digs and capture some points then hold them after some time has pass. It may part of a chain event.
Wondering if anyone else has found any new events?
