Trialmaster bug

Hey!
Playing ssf, got myself 3 ultimatum fragments.
Wanted to try Trialmaster fight, figured out that i had zdps midfight but anyway, happens.

So, during the fight he stops the time and... that's it :D
He forgot that he should also continue the fight after that i guess.

RIP the attempt, back to farming boiz.

Same thing happened to me he started casting atack with 3 blood globes, casted 1st one then he just disappeared while i was still in timestop, i wait for around 1 minute and i got unstuck when he casted another atack with timestop (the one with shockwaves) but he immediately started spamming other atacks with like 3-5x speed and i just died so minus fragments i guess.

Why can't you re-enter this fight after a DC? I got "an unexpected error occured," and was sent to login screen only to have all my progess and all 3 fragments robbed. Infuriating.
