Whenever attempting to enter any zone with an Online character while in a party, my brother and me have to wait for about 5 seconds before the loading screen appears. We can still move around, and then suddenly, sometimes as much as 20-30 seconds later, the loading screen comes.
Sometimes we can’t even enter the next zone at all, getting “entering insert zone name here” forever, and have to re-log and re-try to enter before we can progress.
This issue persists whether we are trying to leave a zone directly, from a waygate, from the map, or teleporting on each other.
It seems to be when we are in a party and playing together.
