Massive Latency Spike upon entering The Harvest (Act 4)

Once I get into The Harvest zone latency spikes upwards in a linear faction up to 15k ms and eventually disconnects. I had somehow managed to get to the waypoint the first time I entered the zone, but from there on I've been unable to play in that zone.
Tried some other zones ex. The Aqueduct, to see if the issue is also present but so far the only instantly noticeable one is The Harvest for me.
Attempted creating new instances as well as switching to other servers but the issue continues to persist.

Same here in any server. The issue started when I switched to a new instance on a new zone (control + click on the new zone and selec "new instance"), after that the zone became unplayable increasing the latency to over 10k+, tried the same on other zones and the same issue occured. For me, this happened on act 7.

PD: Waited for the instances to disappear on their own and joined again, issue disapeared but unsure if that fixed anything

Same for me, any zone with the league mechanic - latency over 10k. Unplayeble
