Running BTA 7.3_04. My PC lost power while the world was open. Since then the world appears red in the world list with "Dimension corrupted".
level.dat is readable.
All .mcr region files pass structural and decompression checks.
The corruption is detected before entering the world.
From decompiling SaveFile it looks like dimensionData.get(0) == null is causing the world to be marked as corrupted.
Is there any way to rebuild dimension.dat or regenerate DimensionData from the existing region files?
