If you are kicked for flying or related, read this

I tested this today with viper. Apparently jailing the "bug victims" before they login is a good way to get unstuck. They still may be kicked one more time, but it'll work after.
If you have this problem, create an alt and ask a moderator/admin to do it.

Random person:/msg mod i'm "X" alt, and I cannot login because of that pesky bug!

Moderator/Admin: /r I'll jail you for a minute or so, log in now.

Random Person logs in. Random person: It worked, thank you!

OR

Random person gets kicked again, relogs, and this time it works. Random person: It worked, thank you!

This is the temporary fix i found, hope it comes in handy.
