I killled the rune imp with Leo, and because the body was consumed it didn't drop any rune loot. Is this expected behavior? If so, then players need to be careful not to use any hero that will consume the dead body (i.e. Leo, Green Cube, Taste for Brains from Zomm, or Incinerate from Ignus). It stinks that a random enemy can be killed and the player not get the reward.
Just be aware.
