Something that's always bugged me about the Crest rules is that if you overstack a depression hex with a unit at Crest, the overstacking penalties apply even when the firer has no LOS to anything in the hex except the unit in Crest. So, if a side has 4 squads IN a Depression and a SMC at Crest, an enemy unit that only has LOS to the SMC at Crest applies a -1 IFT/TH DRM at it despite not being able to inspect the location's contents because the squads IN the depression are out of LOS.
Another ASL physics issue.
EDIT: for Vehicle overstacking penalties to apply, both (or more) overstacked vehicles have to be in LOS.
