Bees won't leave their hives

Bro u better stop playin with me

give me my bees back

When we closed the server for updating, some bees were in their hives because that's what bees DO. But when we updated the server, suddenly the bees can't leave. As seen in the video, they try to leave, but get stuck and end up not doing it. Which is a problem.

please bro i just want my bees back
