This extension fixes a known crash that can occur (usually by malicious clients) when CS:GO's sv_clamp_unsafe_velocities ConVar is set to 0, which is pretty much required for surf servers.

It is similar in operation to the closed-source fix by backwards here, https://forums.alliedmods.net/showpo...9&postcount=39

More info about the crash is at https://forums.alliedmods.net/showthread.php?t=284184

* New in v1.1 - added convar cmdfix_kick to disable kicking upon detection.

* Updated gamedata: https://forums.alliedmods.net/showpo...9&postcount=39

Glad to see this get its own thread! This extension has been key to protecting my servers from exploiters since June, I'm really happy this is getting more attention and hope this helps all.

As always, great work Tony and a big thanks for taking the time to make this promptly available to the community.

It is logged, under /addons/sourcemod/logs/L<date>.log

Example logging:

Code:
L 10/01/2016 - 22:54:30: [CMDFIX] User (ID: STEAM_1:1:xxxxxx | IP: xx:27005) was kicked for sending a corrupt user cmd.

This also seems to kick valid clients.
Is there any way to block the command and not kick them?
