yes it can be very annoying.
The other night I went through 3 houses right out side of bunker [top level houses up the bridge] only to find nothing but ammo and back packs and shields. the last house had a Mozambique. I think eight houses is a bit of a stretch but I've been through five houses before finding any weapon, then finding something in the sixth house.
A rework of the algorithm is needed. The patched that changed the weapon drop of finding great weapons in all area's to what we have now needs to be improved a bit. What ever is causing the weapons to not appear weather it be looting all the time or a bug in the code needs to be reworked.
Even "hot zones" like market becomes very scarce some times.
