I'm playing around with the map generator elevation expression trying to make a map with a lot of nice looking islands.

Just playing around changing parameters I suddenly get:

19.772 Error NoiseProgram.cpp Unexpectedly compiled a literal-number expression and got a non-fake register (16) back

and the game crashes hard.

It doesn't like that your density_expression and spot_quantity_expression are the same value. Is intentional that they are the same, or just some temporary debug stuff?

I'm just modifying values randomly to see what effect they have on the map preview. No real intention to the values at all yet.

Okay, that is great. The fix for this is rather risky, so I won't be solving this so close to 1.0. In the meantime, you just have to make sure that you do not use the exact same expressions for the 4 *_expression properties of the spot-noise and the game won't crash on you. A simple "+ 1" does the job.

Thanks.

FYI: --generate-map-preview is a godsend for testing this stuff.

Thanks for the report, fixed for version 1.1.
