MFFS 3.1.0.175 Bug Server Crash Voltz 2.0.4

[Lithorn]

The MFFS in this version of voltz has a serious bug in SMP only. If a player is supposed to be killed from the shield from being inside the block without holding shift to warp, or if a player is to be killed from tresspassing with an interdiction matrix using a Anti-Player upgrade, it attempts to kill them and locks the server up at times or just crashes. It will always either lock the server up or crash. I have repeated these steps many times and figured out a few things.

Creative Mode is unaffected by the killing effect and dosen't trigger the crash.

This is the only error I have seen come up when the server did happen to crash from the bug.

Calc has stated that he has dropped support for 1.5.2 to work on his latest version for 1.6.x

I am hoping someone can find this of use and get this fixed as the code for MFFS is Open Source as deemed by the original author. His stipulations was that it remain so in such that others can partake of his work in their own way like calc has done.
