My l4d2 server randomly crashes. And I suspect it might have something to do with this plugin someone was kind enough to make for me o nthe fly, a very very long time ago. Untested by anybody except only uploaded on my server.
The plugin reflects any teamdamage, back to the shooter. But not for admin. For admin, he can teamkill anybody.
Could anybody help me clean or see if any changes are needed?
This is the plugin that was made.
