Skip ultimatum trial but still get ascension points BUG

I did this accidentally when I logged off but it can be replicated

You need another person in the party.

1. A player starts the Ultimatum.

2. Complete the first room

3. The player who is not the host goes to the end of the room at the top and places a TP (Not sure if you need to go up the elevator but I did)

4. The host logs out and closes the trial. Dont rejoin the same instance

5. The non-host player quits the game and waits around 15 minutes for the instance to disappear.

6. When they log back in, go to town using the waypoint (NOT PORTAL)

7. There will be a portal in the town that leads directly to the end of the trial and you can get ascendancy points.
