1.153 is a very old version of the game, from 2012. I have never tested the app on it. It is entirely possible that its savegame format was subtly different in ways that break the app - the check that causes the error you're seeing is there to catch similar problems with future game versions.
It's possible to accommodate the format differences in different versions, but I need to figure out what they are first. If anybody knows what the difference is in this case, that would help a great deal. Given the amount of time it takes to reverse engineer data structures from the saves, it's unlikely to happen soon otherwise.
Out of curiosity, what it special about 1.153? Are there some popular mods that don't run on anything newer?
