As I now have been playing on a new PG map for some time, I noticed an oddity with the spawn points. After dying (over and over again ) I seem to always spawn on the same point, regardless of the area I select for a random respawn. On the current map I always spawn zone West 3, regardless of whether I select North, West, South or East. All areas are available (except North 3, which is probably in the water). The map zones West and South have been discovered (North and East are still under FoW).
