Portion of built walls disappearing

[SlightlyOff]

The vast majority of my walls around my small base kept disappearing when I ran one of my guys to town to buy some supplies. The walls were still there blocking pathing, but almost all of them were invisible preventing me from walking up and manning my defensive turrets. Reloading a save made them visible again. I discovered that checking the setting "Fast Zone Hopping" preventing the walls from disappearing. So it seems more an issue with the walls just not being redrawn when jumping back to base. I'd prefer to not leave that option on for the whole game.
It's not a issue now as I have a small base and only a handful of people. Version and computer information below. Save file link below. Windows is updated. Drivers for videocard are updated.

Same problem here as well. Loading fixes the issue, but just temporary... as soon as I leave town, the trouble begins.
