Bee's not coming out of hive

My bees exit their hives all the time but within a split second they go straight back in all the time. I now have 5 hives all full of 3 bees each but they just keep going straight back in. Therefore the hives are always empty and I can't acquire anything from them.

I did 2 of the 3 advancements but now can't do the last one because I can't fill bottles to make the blocks to break my fall.

I have had this issue since yesterdays update
