Steps to Reproduce the Bug

1. Install Enhanced Mob Spawners with Alex's Mobs or/and Alex's Cave
2. Try to kill some mobs from those mods

Enhanced Mob Spawner filename

spawnermod-1.20.1-1.9.3+Forge

Other mod filename (Optional)

Minecraft 1.20.1
forge - 47.2.20
alexscaves-1.1.3
alexsmobs-1.22.7

Extra Notes (Optional)

The server gives me this message whenever a spawn egg should drop :
[Server thread/WARN] [spawnermod/]: Key=alexscaves:notor was not found when trying to access it! Returning 0

Also in the config file, what I'm guessing is the auto-generated part for those mobs is bugged and looks like this :
"alexscaves:spawn": 0,
"alexscaves:spawn_": 0,
"alexscaves:spawn_e": 0,
"alexscaves:spawn_eg": 0,
"alexscaves:spawn_egg": 0,
"alexscaves:spawn_egg_": 0,
"alexscaves:spawn_egg_dee": 0,
"alexscaves:spawn_egg_deep_": 0,

No other mod seems to have this problem.
If the problem is not on your end, let me know and I'll go ask in their discord.

My bad, just saw someone else already brought up the issue and got a response.
I'll mark as completed.
