Hello,
I am a Head-Admin on a server and i have found an issue with Bats and regions. When people ride Bats they can bypass the "Entry Deny". Please fix this ASAP as this is causing a lot of grief to the players of the server. Thank you.

Couldn't you make it so if your going to teleport it dismounts the mob from you or you dismount the mob by force?

I would love to, but the Teleport Event doesn't actually fire if the player has a mount or is inside a vehicle (as seen by the link above).
There's currently an open PR that could fix this.

This is just going to have to wait until teleportation in Bukkit is readdressed.

I can't actually do anything to fix this, as seen here. If I come up with a solution I'll notify you here.

Going to close this as it is a duplicate of #9
