Map Crash

[Okami-Shiranui]

I made a height map on Photoshop, but if i try to load it, the game freezes and crashes. i have redownloaded it once, restarted the computer and the game but nothing has worked. the map was 513x513 and in greyscale

[Ingredient]

Check these

-513x513
-Greyscale mode not RGB mode (Very important)
-One layer only
-Saved in the Terrains folder try in your map folder
-Saved as .png format

Sometimes starting again is an option i take.
