Splitters not working

[ddeath]

Hi there,

splitters are not splitting in the experimental factorio.

Watch blue splitters on left side. It does not fill both sides of belts only one. However the blue splitters on right side are working properly. Difference is that one spliters continues with both belts other with one

That's just how splitters work.

They don't even try to split each lane individually. The take input (both lanes) and do "one to left, one to right" repeatedly.

In your case that leads to all right lane items going left and all left lane items going right. Can also lead to crazy stuff like:

Or actually useful stuff like item filtering with only belts (don't have link right now).
