Need Help with a bizarr problem regarding to custom "gold" weapons

[SirVoid]

Good Day dear facepunch community,
I apologize in advance for my bad english as it is not my native language.

So I wanted to make my gold sticky and grenade launcher a bit fancier (at least for me), so I colored them differently and it did seem to work. I recolored all needed files. The weapons vtf files as well as the cubemap to fit the new color.

On game start up it looked as it was supposed to:

I created my own server on TR_walkway to see how it looks ingame and everything was fine.

Now to the problem: As soon as I join any online server like valve servers, lethal zones vsh server, etc. The weapon looks way too bright all of sudden.

When I then create a server it also looks this way. When I restart TF2 it looks normal again but changes to this bright version when I join a server again.

I don't know what causes the issue I thought maybe it has something to do with the HQ Sticky Launcher mod but the problem stayed.
Can someone help me with this? I have no clue at all why it does this.

Looks like it's not reflecting the proper cubemap. Looks like the work of sv_pure

Nah, If sv_pure would have been on either 1 or 2 it would also force the Weapon to use its original texture as well as the original cubemap so it would look completely normal. Also I know for a fact neither the official valve server nor the Lethal Zone servers are running sv_pure.
