Bob apparently doesn't know what pptpd is. Or what "VPN" means. Or what PPP
is. Or didn't read very carefully.

But he's probably right anyway. The bug is more likely to be in pppd than
anywhere else. It's weird that it would write to wtmp (for last) but not utmp
(for who). Check the config files for recent changes, and if you can't find
the cause, find someplace that gives help with pppd.

An strace of the pppd process during connection setup could be enlightening.
