Hello! Been testing out this modpack that my pal put together but ran into a weird bug. Whenever a villager hits master rank it'll crash the server. When coming back on and try to trade said villager it'll crash the client but not the server. here is the logs from server and client.
Client: https://paste.ee/p/QyH2dS46
Server: https://paste.ee/p/MmPylQAb
