The server maintenance scheduled yesterday has been completed - the issue was related to our server host hardware and it had to be addressed in order to keep the game stable however we would like to let you all know that a server rollback of 4 hours had to be done due to the complexity of the hardware issue.
As our compensation for the said inconvenience, we are temporarily increasing the drop rate in all bosses for a 24 hour period. The boost will be over by 16th March 2018
For more information regarding the boss spawns and schedules,
