delirium will not end in a party when the host dies

as it says in the title.... the delirium encounter will not end when in a party and the host dies. tried ending the delirium on the hosts end. nothing... tried ending the delirium on the joinee's side.. nothing. if it's map specific it is on hive

On Sulfuric caverns the same thing happens, the timer at the end even popped up but delirium isn't stop when the timer reached 0...
