@Liewe_Lullu Thanks for your pln file.
I am looking at it, and I got to say that I have never seen a plan like that.
No wonder the tool is confused.
The problem is that the way you have some inputs that come a factory to your spaceport and some that just transfer from a storage to your spaceport.
The tool is trying to align them but the factory and the storage are fighting each other for the right to align the spaceport with themself.
I’ll need sometime to think about a solution.
