I didn't download the fixed leaked patch, I just did as Holierthanu said. Before I replaced the patch2.xp3 with the Leak one, I backed it up. At the parts where it crashes, save, shut down Fate, rename the patched one and copy the original xp3 into the directory. Then start Fate, load the game, skip the scene and save afterwards. Then delete the original xp3 and rename the leaked into patch2.xp3 again.
And fuck! I'm through UBW! I did this route already. What a shame! There'll sure be no Heaven's Feel patch out until MBAA D=
