There are a few cases in vanilla where certain events don't work on Mayhem and Death Sentence because Overkill forgot to update the level scripting. One instance of this is on Biker Heist Day 1, where enemies don't spawn on the roof.

This mod fixes this and other similar issues by making it use the Death Wish scripting in those instances. This does mean you might occasionally see the wrong units spawn on Death Sentence, which is fixed by this other mod.
