What did you do?
I used the rail planner and mined the rails from which the rail planner starts

What happened?
The rail planner remained open, starting from inexistent rail

What did you expect to happen instead?
The rail planner would close or return to the previous rail

Thanks for the report,

We don't consider this a bug, rail planning is started from a piece of rail, but after that it is not dependant on rail being present
