I send a letter to Michal Marcinkowski some days ago
about this stupid bug, but there was no response.
He doesn't talk about the modification about 1.2 too,
so I will write this down.

I found this bug when I was making original map for
playing with friend.This is serious.I donT want to say that
this is [:-censored]. Its just a horrible bug.
maybe some people are doing this by not meand to cheat.
I really wanted a quick patch for this because there are many
cheaters among my server.I am afraid of increasing cheater
by reading this thread, but i thought it would make developers to
solve problem faster.so i posted it.

Michal's aware of this cheat and it's been addresed in the new version
