Duke3D: Can't throw pipebomb through small opening in Red4
This occurs since r7480 (cdcc13e8), with the behavior changing again in r7484 (eca7133e).
It is no longer possible to throw a pipebomb through the crack in the image below. Instead, it gets stuck inside the crack, and never passes through. Previous to r7480 the pipebomb went through fine. This is essential for level progression in this map.
This is from the map 
. Attached is a cut-down version to demonstrate the problem.
