Delirium anomalies

I've encountered anomalies after I started running deli.

I'll try to explain as best I can:

1. Entered map and started Delirium. It never started - no fog, mob kills not counting.

2. Delirium encounter worked, but bugged my boss encounter Steaming Springs map. Basically my Delirium encounter is ended, but whenever I go near the boss room, the game crashes without error. There is a Delirium some kind of shape or statue right in the way to boss encounter, which I see as my game freezes and crashes.
