Wraith/ghoul/ice golem/etc death notifications
"You've lost a minion" notifications probably shouldn't be played when disposable, summonable creatures die, such as wraithes. It's a normal and inevitable thing, after all. When you summon an army of wraithes, you don't need dozens messages about their deaths a few minutes later.
Game Version:
Steam Public
Platform:
Windows
Can replicate on internal version, but only with ghouls.
Creatures that have a limited lifetime by default (spirit workers, wraiths, frost weavers, . . .) do not seem to trigger any alert upon death. Did not test it with revenants, though.
