There are no raids. They are a bit too OP so they will be turned off until Schaum finds a good was to nerf them.
Lag was bad when I logged on the other day. Will there be any fixes in the near future as it was unplayable?
The lag is due to all the new chunks loading, but when the player count is low (under 10), the server is playable. Once no more new chunks are being generated the lag will stop. That'll be in a few weeks.
