Can't "go to air"

[miranda1000]

If air is set as bedrock stage you can't set it as "go to" stage.
Also, if you insist you'll get the following error:

NullPointerException
Cannot invoke "com.rogermiranda1000.mineit.mine.stage.Stage.setBlock(com.rogermiranda1000.versioncontroller.blocks.BlockType, boolean)" because "overridingStage" is null
