Hi im playing now with Space Exploration and Krastorio 2. I flew to my first planet and when i try to build LTN im getting this massage: LTN Combinator built with auto-disabled services. Rebuilding station or hooking regular combinator does not help. Station remains inactive.

This can be configured via mod setting. By default, stations built via blueprint / robots will be "disabled". This is to avoid trains getting dispatched to a station built before the track to get there is completed, or some other condition that makes the station not really ready for trains.
