In that case, the map had bugs.
It wasn't that buggy... there was a Guard Outpost slightly off to the side, but it was there, and there was a road leading to the center...
The rules don't state that there should be a tech resource if there isn't a Guard Outpost on the road to the center...
When the Guard Outpost is in an unfavorable location, but it's possible to pass by it, then a Guard Outpost is placed off to the side, or even off-road... the situation was similar there...
