I'm not sure if this has been documented but I haven't seen it in this thread. An issue with stratus clouds (the "foggy" preset in the quick-start menu) - happened at KPSP. There are also some minor issues with cloud shadows moving with the aircraft while in flight .. but it seems as if the shadows will be treated in the next update! Anyway, besides these two bugs SMPv2 is great and I've had it only a day.
