Maps are resetting even when explored fully [43,66,72,473]

After the 18gb update on the Xbox recently, the maps are resetting to unexplored after you've teleported to encampment and back. Even when you go to the next area and go back to the same map it resets and no the instance is not resetting because it's just instant reset sometimes. I tried reinstalling the game and clear cache but nothing worked. This is the reference number generated on Xbox - 436672473

Yep, same issue for me. I did a clean re-install, but didn't help. No idea what to do to fix it.

Yeah this sucks, the whole league having to deal with this and it’s starting to piss me off

Same problem here. Is it a realm wide issue?
