When placing blueprint afterwards, before setting parameters to existing coloured station, ghost shows default station colour as expected
After setting parameter to existing coloured station, ghost shows coloured station, matching existing one
After confirming parameters and placing blueprint colour changes back to default.
Expected behavior: Uncoloured stop placed by blueprint should match colour with existing coloured stop with same name.
Uncoloured blueprint
Similar bug was reported in viewtopic.php?p=674864#p674864, but in this case parametrized blueprint already had stop colour set, equal to default collour and bug doesn't occur in 2.0.77 so it's different issue.
Attached are: screenshots if external imgur hosting would stop working after some time
Savegame containing example coloured station and blueprints.
