Laser extending through walls in mp_coop_laser_2 #1250

Describe the bug

In mp_coop_laser_2, if either player places both of their portals on the protruding wall closer to the laser, the beam will go through the portal, activate the first relay, then proceed to extend through the wall and activate the second relay even without any portals there: image

It doesn't seem to just be clipping through the wall either, because if you noclip inside the wall you can see the beam ends where it hits the wall and then starts again on the other side. chaos_iygaZgh9qz

If you offset the portal, it's even possible for the beam to emerge in a completely different position than it entered! image

It's almost like the game thinks there's a portal there, even though there isn't (and hasn't been since loading the map). Additionally, once when I was aiming the laser around I heard one of the turrets in the next room explode, implying the laser managed to extend even further through the chamber walls, but I wasn't able to actually see this happening or reproduce it.

To Reproduce

  1. Open map

How the heck does a bug like this even occur? It's hilarious but at the same time the heck is even going on here?
