My friends and I have a creative world that is our "main world" and a few months ago after the Buzzy Bees update we got "invaded" by a large group of bees. (there were more than 100) and after killing all of them we thought they were gone but every couple days there are hordes of bees all over our city. mob spawning is off and the world is on peaceful. there was also one incident where there was a ton of rabbits in a building. but that was the only occurrence of a large group of rabbits. we don't want to use the /kill @e command as that would get rid of all the armor stands, item frames etc. i'm not sure if it's a bug or not because i haven't heard of anything else like this.
