Reloading with Set Biome renders Plains

[MidgetHero 2]

I have a project set to Taiga, I reopen Mineimator and go back to that project, the biome is still set to Taiga as expected but the colours start with plains until I click on a biome selection again.

Expected behaviour:
Reloading a project with a set biome automatically refreshes world colours.

Problem:
Reloading a project with a set biome uses plains colouring instead of the set biome.

How to cause bug:
Save a project with the biome set to anything other than plains, close Mineimator, reopen the project.

It happens to me too. I have been trying to figure out what is happening and trying to find a solution. I will let you know if I do.
