C-Foam flies through walls in R4D2

[trim delta]

I know that this issue is quite old, I played some levels with this bug, and I had 1 door max, having this bug. But in my R4D2 PE, we had 4 doors having this bug (on screenshots), the zone 100 was the most frustrating

From my VERY limited experience with this glitch, when it happened it usually affected every door I tried to cfoam

And for what it's worth it also carried through a subsequent playtrough, but only tested that twice (was hosting).
