Oh here is an important message from PM:
Unfortunately, a subtle but pretty serious bug concerning hooking functions which take arguments by reference slipped in into our first Metamod:Source 1.6.0 Beta release.
If you are a 1.6.0 beta user, please download the newest binaries (r506+) from
http://www.sourcemm.net.
If you are a plugin developer, make sure that you download the newest sourcemm SDK from svn (mainly the
sourcehook.h file) and release new plugins ONLY compiled with this new SDK.
Thanks!
