Its them spawning at the American out-of-German-bounds-area. I think its simply respawning them else where
Not a bug per se, but I REALLY want the guns of Point du Hoc to spawn like in MP... same deal - Sure the bots wont bother with them, but I will -
Same goes for the German Tanks and Italian airplanes in Hyacynth, and the .30 cal MG in the first 2 bunkers of PDH... I heared Lobo say they were supposed to be there, but they aren't in SP... :-(
