Game when watching demos on train specifically causes the game to crash

ok the game is not crashing because of the demo, it's because the map is broken after the latest update.

@kisak-valve found the issue on the map, the boxes have missing textures
had to launch the map in -tools mode so that the game doesn't crash.
