Bullet tracer effects get an incorrect attachments position of the viewmodel in multiplayer

[Goldermor]

While working on my weapons base, I noticed that the effects of tracers from bullets get incorrect attachment positions from viewmodels when using any viewpunch effect in multiplayer.

Here is an example of the resulting positions Blue - the actual position of the attachment in the world Green and red - the starting position of the bullet tracer

Singleplayer(correct):

Multiplayer(incorrect):

this works with any bullet tracer effect including default egine effects

To reproduce:

Use any SWEP in multiplayer; Set any visible tracer in bullet table; Set self:ViewPunch( Angle(-10,0,0) ) or more in PrimaryAttack function.
