DELIRIUM MIRRORES NOT WORKING

For the 5th time today alone i went into a map with delirium, passed trough the mirror and activated it. Cleared the map (or part) never spawned delirium mobs and the delirium reward never went up, even clicking the end delirium button didn't give me rewards. Please fix this cause it is just a waste of time going into a map hopping to get delirium rewards and not getting anything.

I've had the same issue.
