its also hugely random. i had 3 raids events in 1 hour 2 days ago and havent had any since then. there is a CHANCE for a raid event. its not 100% to happen.

interesting, our main base is in meadows but the swamp and bf are very close. One time there was a bunch of fullings and two brutes outside our base at the swamps edge but we never had the words saying we were being raided.
