I can't get loot from Hullbreaker. I've killed a few of them, but he doesn't drop anything except exp. Just nothing. (I know his loot is highlighted in white and can float to the surface, but I still can't find anything.) Since trying to kill him in melee is insane, I fight him with a fully enchanted Galena Gauntlet. At first I thought that was why the loot wasn't dropping (like the game doesn't realize I killed him), but I left him with a few hearts and finished him off at close range - the result is the same: no loot. I also tried killing him in another world in creative mode: sometimes loot appeared, sometimes not. I don't understand why and what should I do.
