So this happened two times today.
The first time i was doing fractals with some friends. We had just finished the third one which was the grawl fractal, when instead of beeing ported to the final fractal, we landed in Lions Arch and the fractal was gone.
Second time was in the Silver Wastes. I was doing the events on a rather empty map. Whe had finished The Breach and were waiting for the attack on VineWrath to begin.
Suddenly I was ported to another SilverWastes map where the events were at 0%.
And I wasnt the only one. There were a lot of people on that new map that had just been ported there from another one, many from the map i had been on.
I hope this gets fixxed soon as it is a really annoying bug that is strongly demotivating
