We used Eldritch Mobs for a while in our custom modpack but decided to remove it for now because most of the players didn't really like it. Now after removing the mod from the pack I noticed that the server log is getting spammed with the following messages:

Failed to deserialize component: unregistered key eldritch_mobs:eldritch_modifiers
And
[Server thread/ERROR]: No codec for memory: minecraft:dummy; No codec for memory: minecraft:dummy; No codec for memory: minecraft:dummy; No codec for memory: minecraft:dummy

I'm not sure if that second one has anything to do with it, but I'd like to a least fix the first one. Do I need to remove something else or is that because there are entities of the mod left?
This is on Minecraft 1.20.1 and we used the latest version as of writing this for that version.
