If a player is in the front seat of the mini, he/she teleports to the owner of the mini (with the mini) who use /gmini.
Players use each others mini's so they can teleport :)
@the creator of the mod: Is there a solution to prevent this?

If using NTeleportation, have you tried with the config for that including "InterruptTPOnMounted": true ?

No, because i don't use your NTeleportation mod.
Maybe you can script:"InterruptTPOnMounted": true" into My Mini Copter.  :)

Maybe you could install NTeleportation and disable everything EXCEPT "InterruptTPOnMounted": true" :)

Thank you, but isn't wierd that you must use a mod to take away a glitch in another mod?

It was just a question.

Yes, i know rfc1920 and you mod makers are doing a great job!
I thought that it was possible to adjust the MyMini mod to remove this glitch.

0.0.9 should remove this exploit.  I'm sure that if it works someone will want that to remain as an option.
