My Trials of Sekhema starting area is stuck in another server ?

So I joined someone in Trials of Sekhema area to trade with them. I joined their party, used the blue icon on their portrait to teleport to them (which took me to Trials). Did the trade and then left.

After that interaction, whenever I go to Trials on my own, I have the same network lag. I'm talking about the starting area where you insert the Djinn Barya. No other map area has this issue and they play normal.

But when I go to Trials area, I have a lot of network lag. From what I can see it seems to be stuck on that other player's server location, which must have been in a far away region.

I joined a public party, then used the waypoint to go to Trials area. This fixes it temporarily - The lag is completely gone and it's back to normal. But if I leave the area and re-enter on my own, the problem is back.

Restarting the game and logging in on different regions doesn't seem to help so far. Creating a new instance of this particular area isn't possible.

I seem to be stuck with this issue for now. Please help.

I haven't done a lot of testing so I might be coming to bad conclusions, but it seems like this is the issue.

I used the F1 overlay and it shows me the network lag. It shows 300+ whenever I'm doing anything.

To clarify.
I join a party, the port to Trials - back to normal.
I leave the area, leave the party, then go to Trials - lag again.

So around 8 hours later this sorted itself out.
