Will do. I snooped around. I would say the data file update from 1.7 to 1.8 is not parsing properly.
That is an unwanted tech advice. You can ignore :)
Always happy to hear it. What you say is quite possible - I changed some of the data in there. The save data has a version number saved with it. If the version is greater, it's supposed to create a new save file, and copy over any new fields that exist now into the old save file. But I probably messed something up somewhere, or didn't update the save file version or something.
