There are a few console commands that you can toggle for consistency errors. I have them in my autoexec.cfg so they automatically run each game I start. I don't know if they are required for server configs to enter them as well, but I use these:
sv_pure 0
sv_pure_kick_clients 0
sv_consistency 0

Regarding the reload duration, yes I have noticed this with mods too, I think and I am speculating here, that this happens when the reload duration of the new model's animation is not the same as vanilla. Yes there is a reload duration variable in the scripts, but I would have to do more experimenting to match them up to new models if they use an altered one. In any event, if you discover any ways around these or fixes, I am all ears. I'm not an animator but I can putt around and mess with scripts, etc.

Thank you for the feedback.

You know what, I really love the original mod, it's the very ideal mod for me, but the pity is that it has consistency issues when playing online. So much appreciate to your work, though I haven't tried it yet.
By the way, in my opinion, what caused online consistency problems may not be that obsolete css weapon unlocker, but his custom weapon script, because I found out that when using the original mod, the reload speed is faster than the vanilla SG552, and it will cause:
1. It may work online, but the reload animation finishes before the gun is actually ready to fire
2. It may directly not work online (system telling you that there's consistency problems)

So I don't know whether you have checked the reload problems, but thanks again to your work, because I really love the original mod
