Couch Co-op Mapping Crash/Bug on Death (also affects trials of chaos)

When doing maps in couch co-op, if one player dies, the screen will eventually go black (UI elements/health globes are still visible) and the living player is unable to progress. Game must be restarted to get rid of it.

This also happens in trials of Chaos. This is also very annoying, as you are essentially forced to do them solo.

In both cases, if either player dies the map/trial is failed. The other player should have the opportunity to finish the map/trial, particularly as these activities are reliant on rng to even have the opportunity to do. Pretty game breaking, and discourages couch co-op.

Also, up until the time the screen goes black, the death artwork (bloody streaks above/around the health globes) never goes away, obscuring part of the screen. Not sure if this is related to the bug or if this is intended. If intended, it's stupid. It should fade away after like 5-10 seconds, max. We know the other player is dead. No need to obscure the entire bottom corner of the screen behind useless artwork.
