This relates to a world that was created in 0.11.17, then I upgraded and continued to play it in 0.11.18.
The problem I am seeing is that the map (both mini-map in top-right corner and the full map opened by pressing M) is no longer updating. It shows the world as it existed at point of upgrade, and does not show any new structures.
I performed the following to see whether they would resolve the issue, but they did not:
* Save/load to a new file
* Restart Factorio
* Restart computer
The following screenshots demonstrate the issue: http://imgur.com/a/QycqT
Both shots are taken from exactly the same position, just after one another. The first contains my steam engines and green circuit production, but looking at the second you see what the land was like in the past, before the steel and green circuit production, before the bus was extended, and with a vertical stone wall plus a few turrets. That stone wall has in reality been pushed far off to the left.
The following report may be related. It relates to expanding the height of a map, but I wonder if the real issue is that the map *is* expanding, but the new terrain just cannot be seen as the map hasn't updated to show it:
