I've now had two ironman (Trial of Iron) runs ended after the main PC died but there were still other party members alive. The "you're dead" screen popped up and the save was wiped.

 

My best guess is it's either caused by the dead PC being too far away from the living party members or it's something to do with fire damage as it happened one time in the drakes/bats fight in the volcano and one time in the fire naga fight (with a completely new save file, new PC, etc.) further to the northwest in that archipelago after the pc was killed by a fire trap.

 

The easiest fix on your guys end here would be for the game over screen not to delete the save, allowing people to alt+f4 out if they wanted to keep their save.

Hello roguelike,

 

Thanks for the post! Ironman is meant for this mode as explained in the New Game menu. 

 

best,
