I've been playing EB 1.0 for several hours, but all of a sudden I get the following error message whenever I start up the game:

"Script Error in eb/data/settlement_plans/roman_town.txt, at line 69, column 1.

Border wall features - found more than one adjoining feature, there must be overlap somewhere (position (34.000000, -224.000000))"

I haven't touched any of the game's files, so I have no idea why this has just started happening. Any idea what I can do to fix this? Thanks.
