Nothing gameplay-breaking, just observations in case someone "official" is actually monitoring this forum for game defects:

NCR supply crate (summoned with the emergency radio) spawns hovering so high above ground you have to look up in order to access it.

Centaur and Radscorpion corpses sometimes stick out of the ground a very long distance from there the actual corpses are.

At certain places, frag mines are untargetable and can be neither disarmed nor detonated by gunfire.
