This is a strange issue indeed, if it's the mod's fault somehow then I would love some insight into why exactly that is the case. The save in question was being played with version 0.0.5 of my mod pack. After updating to 0.1.1, which added several new mods including More Floors, the save became broken and trying open it caused a hard crash. Even using the original mods resulted in the same problem, which shows it wasn't an issue with my compilation method. Finally we managed to narrow it down to being caused by the mod More Floors. I tried removing it, saving the map, and re-adding it but that still crashes once I zoomed out (rather than as soon as loading). The only way to keep going was to play without the mod.

I can try to get a save from before the issues if needed.

Fixed for 0.15.

The problem is before you had pictures for larger tile sizes (2x2, 3x3, 4x4) but now you only have a 1x1 image and the size of the saved tiles is still saying 2x2 so it tries to render the 2x2 image for the white-concrete which doesn't exist and it crashes.
