Hello
If I remove only the first or the last element of and completly filled underground belt by hand I get all Items from the Underground belt without the 4 from the remaining undergrund belt piece
If I remove the last underground part in transportation direction with a robot then the robots take 4 pieces from that deconstructed underground and the other items remain in the underground.
If I remove the first underground part in transportation direction then the rebots takes all Items from the underground belt without the 4 from the remaining undergrund belt piece.
why is this different?

I tested it on blue belts.

you can get some comress fun if you remove the last from a long tunnel and then place a new one on the shortest place

Thanks for the report. It was changed with the transport belt optimization due to how it works and I don't consider this worth reworking to try to change back.
