Description of the bug

If a bomb cube explodes while redirecting a laser, and that laser then meets a reflection cube as a result, the game entirely crashes. This happens both in-editor while quick testing, and in the published chamber.

Expected behavior

This interaction shouldn't behave much differently from fizzling the bomb cube-- and I've actually tested that too. With the same setup, respawning / fizzling the bomb cube does not trigger this crash. The bomb cube gets removed, and the laser can continue forward until it meets the reflection cube, where it gets redirected as normal. The bomb cube exploding should yield the same result, rather than crashing.

Steps to reproduce

1. Place a reflection cube somewhere in the path of a laser, so it redirects the beam.

2. Grab a bomb cube and set it anywhere that intercepts the beam EARLIER than the reflection cube.
   Proper placement (will consistently trigger a crash):

Improper placement (will not cause the crash):

3. If done properly, once the bomb cube explodes, the laser will directly hit the reflector, and crash the game.

Logs and Reports

Additional information

I've done this with bomb cubes set to both 03 and 05 sec timers, and that didn't affect the consistency of the crash at all. I haven't tested the other timers but I imagine it (probably) wouldn't change much.
I'm using the default Portal 2 style, I haven't tested any other styles.

Huh interesting. I'd guess some logic in the laser code tries to access the old cube and crashes because it's already been deleted. Maybe we should just teleport the cube somewhere out of bounds when the explosion effects appear and then wait like a half second before actually deleting it.

Ohh, this crash, actually ended up finding and fixing it in P2:CE. Teleporting might work, not sure.
