Certain locations have unstable latency while others are fine

My ping inside of the vaal temple is horrible and it doesnt matter which server i switch too while, my ping in the temple lobby area or other towns are just and areas are just fine, normally just creating a new instance of the zone fixes the latency there but u cant do that in the temple without closing it and loosing all of your rewards.

Same thing happened to me. It's the exploiters crashing the instance servers

Okay, thank you, this means I'm not insane. My latency will just spike like crazy when I'm in certain areas. Sometimes it clears up on its own, sometimes it clears up if I logout/login, but there's really no rhyme or reason to it. Good to know it's likely a backend issue on GGG's end and I'll just have to deal with it until they resolve it.

It's really annoying though.
