Describe the bug
No solution found in the wiki.Coins and biological spoils cannot fall at the same time. The configuration has been changed and all biological spoils have been replaced with coins, but the original biological spoils disappeared. Is there a way to have both.

To Reproduce
lightmanscurrency-1.20.1-2.1.2.4b.jar

The coin drops do not in any way affect the default item drops, and during testing the mobs have dropped their default drops at their normal rates (usually tested on zombies, so rotten flesh, etc.) at the same time as the dropped coins... If this is not happening for you then another mod must be messing with the entity death event, and/or you're just getting some really weird RNG.
