Here’s more info on the stability issues on Xbox. Funcom is aware of the issues and working on solving these problems. When I go online, I usually wait for the server search function (the three pulsating circles) to finish before joining the game (I wait for the “Y refresh” button to appear). If my search results are all “0” of 40 I refresh and wait for the button to appear again. I’ve been able to play online for well over an hour with no real issues.
Hope this helps.
