GetCollisionBounds( ) returns different values for weapons client/serverside

[Acecool]

I designed a system that makes a user look at a weapon on the ground and tap use to pick it up, or hold use to swap if they already have that class of weapon in their possession. I noticed that that sometimes I would have errors on the client-side where it wouldn't show the text on the screen, and other times the text on the screen would follow the client even when not looking at a weapon. Additionally I noticed that sometimes while looking at a weapon and trying to pick it up, the client would report that I should have picked up the weapon but I'd end up with a different weapon in my possession.

I narrowed it down to GetCollisionBounds not reporting identical values client and server-side.

Here's a 10 minute video on the subject: http://www.twitch.tv/acecoolco/b/425434019
Go to the 8:25 mark if you want to see weapons spawning with this code in init on client vs server:

Remember, I recoded print so it prints nice vectors out and handles different data types for ease in debugging.

First line on client/server is GetCollisionBounds min, the next line is max. The third line is trying the same with OBBMins, fourth with maxs, fifth with mids.

The last 3 lines can be disregarded because they report the same as GetCollisionBounds. My computer locked up due to the video encoding, if you like I can do another video with just two lines per weapon and output the weapon on the server/client with all the CSS weapons.

One of the addons I have, assault weapons pack by M9K, has a weapon that reports "normal" values on the client, but on the server it reports something along the lines of 0-6000, 0-3000, 0-11000 which is quite a ways off. The bounds that appear to be used are not the client-bounds, but the server bounds, including when using a trace.Entity to see if you're looking at it client-side.

    local min, max = self.Weapon:GetCollisionBounds()
    local mins = self.Weapon:OBBMins(); 
    local maxs = self.Weapon:OBBMaxs();
    local mids = self.Weapon:OBBMaxs();

    print( min ); 
    print( max );   
    print( mins ); 
    print( maxs );
    print( mids );

Quick update; I output an entire array of information on the client side ( I did this because the server was outputting radical information; seemingly way out of range; but this method has no effect in correcting the collision bounds it seems or the Trace.Entity bounding box. )

So if the array exists with the weapon type, it loads it but it doesn't appear to have any effects on the weapons with the overly ridiculous sizes.. I tried self:SetCollisionBounds as well.

toprint is the internal function which works with my print function to return nicely formatted data.

This is on SWEP:Initialize, shared.

    if ( self.CollisionBounds[ self.Weapon:GetClass( ) ] ) then
        local _cb = self.CollisionBounds[ self.Weapon:GetClass( ) ];
        self.Weapon:SetCollisionBounds( _cb.min, _cb.max );
    else
        local min, max = self.Weapon:GetCollisionBounds()
        print( "SWEP.CollisionBounds[\"" .. self.Weapon:GetClass( ) .. "\"] = { min = " .. toprint( min ) .. ", max = " .. toprint( max ) .. " };" )
    end
