Trial gone after finishing stage

[JamieF]

I dont know if anyone else has this problem, but i just finished a 10/15 trial monster and i got the reward for that lvl. But then, poof, i got the window in which you can start a new trial. What happened? Restarted / rebooted, no luck..

Happens all the time. You're going to have to suck it up and repeat the stage again. Wish I had a solution for you.
