🐞 Mob AI Bug

I am not sure why or when does this error appear .... but for me it just appeared during a test for my plugin with +60 players .....
In my plugin ... I made some sheeps and cows spawning every few seconds in an specific location and not to spawn anymore when mob limit is reached
the error for now was just a bug message showing in the console ... didn't really affect the gameplay .... but I was just wondering why did it happen
