Height Map Keeps Crashing!

[EmptyHabits]

I've made height maps before, and they've always worked. The last 2 height maps I have made have crashed in the Map Maker and I don't know why. It's in grayscale mode, it's 513x513, and it's png.

Make sure these other things are checked off your list:

-No alpha channel
-ONE layer (I can see in your photo that you only have one layer, but make sure~)
-No spaces in the name

Merge all of the layers together, then go to Layer > Transparency > Remove Alpha Channel.

You could also right click the layer and scroll down to where it says "Remove Alpha Channel". It should work after that.
