[TF2] [MVM] Projectile Penetration collides with func_brushes

[gabrielwoj]

Hi there. There is an issue with the Projectile Penetration upgrade in Mann vs. Machine where weapons like Huntsman and perhaps Crusader's Crossbow break themselves in the air (in certain spots) if the Projectile Penetration upgrade is purchased. There might be other weapons too, but I often notice with Huntsman due to utilizing it more.

From what I recall, this is the projectile colliding with an invisible entity used for func_brushes. I believe this is not related to the Wrap Assassin's bauble break itself in the air (as that can happen with any map without the upgrade), but perhaps fixing one might fix the other.

This is definitely damming for custom Mann vs. Machine maps that utilize said entities, and it can also hinder regular maps if a community server utilizes custom plugins that enable upgrades (or has a custom map with upgrades on them). I will see if I can record some footage of a map that has this issue.

I think the best example of this is the barricade on Rottenburg, standing in front of it with the Huntsman and shooting towards where the robots drop causes its arrows to break on what seems to be the air.
