Been like this for days. I have been disconnecting all the time. Here are a few steps I did to try and fix it, but did not work. Maybe it will work for you.

1. Put all graphics to low quality.
2. Fresh install of game.

All I can think to do on my end. I just think the server is absolute trash, and the devs for some reason can only do 1 patch a week, so MAYBE they will fix server first thing..

I am getting it too especially when doing expedition. Maybe you are right about the absolute trash server.
