Bombus Terrestris (the type of bumblebee in the game) useally live in abandoned rodents nest underground, inside a old hollow log on the ground ect. They ar not using hanging nests like the one previously in the game (and still can be seen in the treetop).

Ideas for a beehives:

A in the ground half buried  hollow log with a endhole like those in the woodstack the termites live in. The hive is horizontal only but goes deep through the entire log.

A "cavish" hive at the end of a small tunnel with entrance hole in the flowerbed stone setting at the right part of the garden.

An old teracotta flowerpot flipped sideways and half buried in the in a waste pile of green and trashed flowerpots in the upper garden.

I would like the bee hive to be up in the tree that would be awesome
