Hopefully this bug report is useful. In my debugging, I made a mistake, as you'll see, and the information may not be complete.
A week or so ago, I saved a game that was then not loadable by Simutrans. Figuring I wouldn't waste anyone's time, I then did a svn up, rebuilt and tried again (to make sure that the bug hadn't been fixed in the latest svn). Sure enough, the game still refused to load. It then occurred to me that the bug might not be in the loading, but in the _saving_, and I hadn't recorded the version # that had saved the file.
I didn't experience any computer events involved with the problem (i.e., no computer crash or anything like that)
Anyway, I've posted the offending .sve file online so if anyone wants to investigate, they can:

Hope this is helpful.
Yes last week or so there was for a short time a version which produced broken savegames. Sorry.
No problem. The main reason I play using svn/head is the hopes of helping find bugs.
Probably been said a dozen times before, but thanks for the great game.
