I am not sure how, but sometimes I get the same location back in horrorguessr after advancing, I can even move in it so it is not frozen or similar. However, in reality the location different and I get rejected: the last run I got back winnipeg, everything looks the same as the last round and I can move but the expected location to guess was serbia and I lost in confusion. I was playing in chrome on windows 10 on my lenovo laptop, and this happened to me multiple times but at first I did not catch on. This particular instance was after a boss fight the next normal round, after day 40. I do not recall this ever happening before the latest patch and I have played quite a bit before and after.
