I teleported with a teleport stone to a place far enough away to corrupt more than half of HP.
Then I went back.
I logged out once and logged back in.
Neither way did the summoned corpse appear.
I had tried the method you described earlier than you described, right after this problem occurred.
I am posting in this forum because the problem still persists.
