Bees don't get back to his hives

This issue is far from resolved.  On my server, we have one bee hive with three bees in it.  Even when there are flowers near the hive, the bees eventually, even after filling their butts with pollen, go for an explore heading North or Northwest.  And they seem to lose track of the hive.... and keep going until they're long gone.   I have lost several bees this way and have had to re-breed in order to re-fill the hive.  The only way to keep the bees from running off is to wall them in completely.
