Alright, I uninstalled everything. To be safe, I even uninstalled RTW. Reinstalling everything again including 0.81a v2 resulting in the whole thing working fine. That was the first time. The second time I booted up the game a few hours later resulted in exactly the same problem. So surely you can't be telling me that my install has become corrupted -again-, less than five hours after it was solved, and that it corrupted exactly the same file again.

Here's the error message.

'Script error in /eb/data/settlement_plans/roman_fort.txt at line 37, column 1.

Border wall features-found more than one adjoining feature, there must be overlap somewhere (position -1.#IND00, -1.#IND00)'

Any idea how this happened? It actually managed to load immediately after I played, and I managed to get some gametime in. But after I went out for awhile and came back to continue playing, the same message plays again. I am really quite irritated, since I just wasted the entire morning uninstalling and reinstalling to no avail.
