Today I tried to do guild trek 1st tier. After I started the mission I lost the ability to travel to the other maps. I just clicked the wp and nothing happened. I was still able to travel to wp inside current zone, and I also was able to change zone through the portal (between zones). Once I stand down the guild with active GM I could map travel as always. If you unsuccessfully try to map travel while representing guild with active mission the ability to wp is blocked and you need not only to stand down the guild but also to relog. I was doing this mission alone.
