As you can see there is a lot of honeycombs at the floor, and this is being caused because of a glitch where when you copy the bee nest's NBT(something like that) and paste the NBTs at another bee nest, the bees inside it(and of the original nest) will try to constantly leave and enter the bee nest, causing a lot of noise. In my case, the observers above them will constantly update too, making the honeycombs(or honey bottles if there are some in the dispenser) leave because of the dispensers behind the nests being constantly used. Somehow, the honey level inside of them will never reset, but at the debug menu I can see the level quickly resetting and increasing.
