Ive got this issue as well, and ive made similar observations. Sometimes i can play four hours and not see it once, sometimes its 10 mins. Ive noticed that restarting the game sometimes helps, but theres some pois that seem to permanently be stuck in this state. I always figured it was something with the lod's but idk much about it. I only started experiencing it after the move to a19, but now even if i revert back to a18 it has started there as well. Really hope its fixed as it just removes any desire to play.
