Delirium issue with hive fortress

Entering a hive fortress immediately begins the delirium end timer. Maybe intentional but seems pretty bad if running linear maps with Descent into Madness atlas keystone with the fortress often spawning closer to the start of the map.

I do find this really jarring, every other thing in maps either pauses the delirium timer like a betrayal research / harvest, or else is a separate zone like vaal side areas. If this is going to become core this probably needs to be changed.
