- Build a splitter/merger.
- Build a splitter/merger on top.
The 2nd splitter is not oriented the same way as the first splitter. There seems to be a separate (but non-similar) orientation for the splitter/merger when it is "placed on the ground/foundation" vs "placed on top of another splitter/merger".
And it's hugely annoying it's doing that.
If I build a splitter/merger, and place another splitter/merger on top if it I expect both to have the same orientation of inputs/outputs.
