Check the attached images.
1st image shows layout I have. I produce 'left halves and right halves'.
If I combine left and right halves down the line AFTER passing them to my stacker array (so effectively only left halves are given) the preview still thinks it is possible for right halves to also make it there. despite those only existing later on the space belt.
as you can see only the red line will go there, the green line does not. If I remove the space belt combining the left and right halves there, the preview will be correct.
