I've been trying to get Custom Weapons X working using the guide here:

https://gamepro5.com/programs/tf2_cu...eapon_creator/

However, even if I try different versions of TFUtils, the server console for the ServerManager always throws the error:

L 01/14/2024 - 16:04:50: [SM] Exception reported: Failed to set up call to CTFPlayerShared::IsImmuneToPushback()
L 01/14/2024 - 16:04:50: [SM] Blaming: tf2utils.smx
L 01/14/2024 - 16:04:50: [SM] Call stack trace:
L 01/14/2024 - 16:04:50: [SM] [0] SetFailState
L 01/14/2024 - 16:04:50: [SM] [1] Line 245, scripting/tf2utils.sp::OnPluginStart
L 01/14/2024 - 16:04:50: [SM] Unable to load plugin "tf2utils.smx": Error detected in plugin startup (see error logs)

What I find odd is that IsImmuneToPushback is on Line 235, while the "library" line for Fire is Line 245, being mentioned here. Does anyone know how to get this working? I really just wanna try my hand at messing around with stupid weapons, like (for example) a shotgun that does a lot less damage but has a bigger clip and fire rate. I just wanna mess around, and this is really annoying.

Please, if you have an answer or even a possible solution, say it. I need help.
