there aren't any pings visible on the map currently other than surrounding my base like the ATV and stuff, so either he's out of radar range or he's just straight up gone

Have you checked each ping personally? I know it may sound redundant, but I did see someone suggest to check out your windows, so checking the pings close to your base might be worth looking into, as well. Especially when things on the map appear close to your base, it's hard to determine what's new, what was there, and what wasn't.
