Hey guys.
Every time i placed a MFSU or a Forcefieldblock or anny other modblock , i get crashed !
I got a fix for that problem ! Replace this Jar File with you're exsisting Jar file on you're Server: http://mcportcentral.co.za/wiki/index.php?title=Ports_for_1.2.5 <= use the Build 162 and the internal Server error is Fixed !
