Copper Citadel Bug

Basically i beat the boss. Was supposed to click on Asala but some rogue particle apparently instagibbed me before i could click on her. Now The Map is finished but i cant reacces the boss arena cause its beaten but not animation killed by asala? Especially in Citadel fight theire should be a way reenter or restart the fight i f something like this happens.
