Previously Placed Map Content Isn't Showing in Map Editor

[FennecRaptor]

Hi,
While trying to fix issues related to my map not saving due to the 1.38 update, I somehow managed to make all the roads, terrain, and models disappear in my map. Originally, my map looked fine but wouldn't save (though this is fixed now). To see if I could get a different map to save, I opened usa.mdb, however, all the roads, terrain, and models weren't visible (though the map sectors were still showing). When I then reopened my map, all the roads, terrain, and models had disappeared in it too, though the map sectors were showing just like in the usa map. All this happened while the base folder was still named base instead of base_map. Now that the base folder is named correctly, the content of my map still isn't showing.

Does anyone have any ideas on how to fix this,
Thanks.

Update: The solution to this problem was to uninstall and reinstall the game. I'm still not sure what the root cause of the problem was, but reinstalling the game caused all the content to reappear.
