World file not opening

[staticfox]

I believe I was playing this map in an older 1.4 patch, but I didn't re-load it in to latest in case this was something fixable on the TerraMap side. Built from master using build.bat 1.4.13 (though sources on master say 1.4.12 yet the release is 1.4.13, I tried build.bat with both just to be sure + also tried your release build with the same result).

System.Exception: World file tiles list start is not where it's expected to be. Expected: 3273 Actual: 3274
