0.41 Not able to move characters past a point?

[JustifiedDeath]

So I was playing the game in .40, built some walls and stuff. I updated to .41 later after I saved then crashed. I loaded my game and started researching again, noticing no patrols or caravans going near my outpost (In between Trader's Edge and Brink).I got attacked by some dust bandits and ran to the nearest town(Traders' Edge), and found nobody there(bug from crash-saving), so I was running back towards my outpost and then started on my way to Brink, seeing a patrol of guards there. My characters wouldn't go past the mountain between Brink and Trader's Edge, sort of as in an invisible wall. I saved and loaded, same problem. I put new batteries in my mouse and restarted Kenshi, same problem and no solution. I attached the save file here.

Did you build a gate? Did you also dismantle a gate? Thats probably the cause.

Should be fixed in 0.40.2, but you will still have problems until the pathfinding data regenerates itself for that area. You can regenerate the area by building or dismantling something nearby. After that it shouldn't happen again.

I did not build a gate, only walls. The interior had a mine, processor, shack, storage, and research benches, nothing else.
