Okay so i killed about 15 Spirit and i got 0 ectoplasm and according to the wiki it says that it should always drop 1 and a small chance of dropping 2 and yes i am using potions to kill them. Is there a way to fix that or a update with an entry in the config to change the drop rate

Can you reproduce this with only random things installed?

Hi lumien, I've tested the issue in an instance with just Random Things installed and the ectoplasm drops normally. However I was able to reproduce the issue in the "All the Mods"-Pack v2.56 for Minecraft 1.10.2 with forge-12.18.3.2297 and random things MC1.10.2-3.7.7.1. When I kill spirits in survival, they don't drop their ectoplasm, but when I kill them in creative (both times with potion) they drop the ectoplasm as intended. Killing them with the spectre sword always drops the ectoplasm.
