In my current world (seed 5349), I've planted well over 50 birch trees with flowers next to them. I have yet to see any bee nests spawn when the trees grow up. That's quite a bit out of the ordinary.

Since the expected wait time is 20 trees, this could be a regression.

Can anybody else confirm whether bee nests next to birch trees (with flowers) generate at these experimental levels? If one person can confirm that they generate, this ticket can be closed as just bad luck. But if nobody can confirm generation, ....
