Whenever there are 2 map bosses, they do not drop anything when killed.

Whenever there are 2 map bosses, they do not drop anything when killed. This has happened multiple times to me. It happens when you are fighting 2 of the same boss or bosses like the necromancer and his elephant thing. I also have the thing which lets me track how many enemies I have killed in a map and when I kill those bosses number of unique enemies killed stay at 0. Their deaths seems to not register.

I'm not entirely sure about this one but it might be happening when those bosses are killed at the same time.

I can confirm there is no loot dropped when you kill both bosses at the same time. Happened to me many times.
