mobCaptureCardKillDropDenyList=minicraft:minecraft:creeper
does not work on aternos

This should be mobCaptureCardKillDropDenyList=minecraft:creeper, not mobCaptureCardKillDropDenyList=minicraft:minecraft:creeper.

I assume you meant minecraft:creeper.
If that’s not the case, please provide more details.

sorry i meant mobCaptureCardKillDropDenyList=entity.minecraft.creeper (i have seen it on the creeper card)

i tried mobCaptureCardKillDropDenyList=minecraft:creeper and does not work

btw I am using the version easy_mob_farm-fabric-1.21.5-Fabric

Just to help with troubleshooting:
Have you updated the changed config on Aternos and restarted the server afterward?
Please note that the restrictions and other settings (like mobCaptureCardKillDropDenyList) only take effect after a full server restart.

Also, please double-check that the config is the same on both the client and server, especially if you're running the mod in a multiplayer setup.

Let me know if that helps!

on aternos you can edit file so i did it. then I tried the /reload command and full server restart (Shut down and Boot up).

I have not changed config on client so i will try it

now it does work
