The new core patch removes repair / tether / fitting. You did not change the Show Info Services tab. A fort still reports it has Repair and Fitting on the services tab despite not having it.
The only way to find this out is to warp to a structure and click on it, to see the “Core Absent” message. There is no way to pre-plan a flight route.
The services tab already changes based on what services are available to you, cores should not change this. The Show Info should not just lie to players.
Please post in the above thread - the Devs who are working on corrections for this release will be checking that thread. Also remember to submit bug reports in-game.
