The purges used to work well, then funcom “fixed” them, haven’t worked right since. Of the last 7, I’ve had 2 actually worked right. The rest either spawned in side my keep, or got dropped on top of it.
Fauna walked through all the time, the avalanche purge spawned literally in the middle of my base on the second floor. By the time it was all over my base was leveled and I had lost all my thralls. Took 3 months off.
