[0.91.9]Slavemongers unable to deliver slaves

[Stealthkibbler]

This happened in Waypoint as the Slavemongers attempted to deliver my group to the Holy Mines at the far right of Border Zone, I think the problem was that there is no road going to those mines, The Slavers attempted to navigate into and over the mountains that you naturally cannot really get through without running into autopath issues, halfway there the Slavemongers just stopped and became aimless (I'm pretty sure the issue with aimless autopathing is well known since I've read about it a bit in other threads). However randomly as my characters were following them they immediately began to beat them all into unconsciousness when they all still had the obedient slave status and were following master. Then one slavemonger began 'Delivering prisoner to the nearest cage', then the rest of the group began to move again and he ran back to follow leader. Within under a minute they became aimless and stood there for a solid 10 minutes when I tabbed back in to look, they were still there so I started a new save.

I've also seen many escaped slaves roaming waypoint around day 20-50, I dont believe the slavemongers around waypoint are able to deliver slaves at all, considering that back in older versions I've managed to see large groups of escaped hungry bandits crossing through my outpost, which doesnt really make sense for so many of them to have escaped, some still with very fresh injuries.
