Guild Wars 2

Since the last patch,and after 10 ,15 minutes in the game
I loose the ability to access the TP.
When I try to open it ,it just stays on the empty loading screen
with the loading circle icon.
In order to restore access I have to restart the game.
Then I can open it,but then after a while it becomes
unresponsive and the only way to fix it to restart the game.

This is getting old.
Every single time I need to access the TP I have to restart the game.
