Trial of Chaos Enemy spawn

i just attempted a trial of chaos run, where i hit the "eliminate all enemies" section again, but this time 2 enemies spawned on the end platform and i was unable to reach them with my monk,and the platform wouldnt lower until i killed ALL enemies. i had to remove my armour so the traps could kill me and i could get out of the trial.

This is still an issue. Happened today 0.3.0b
