Pre 2.0/space age behaviour:

Place stop 1, train begins moving to stop 1.
Place stop 2 before train has reached stop 1.
Train continues to stop 1, then proceeds to stop 2.
You can queue up temporary stops

Current behaviour:

Place stop 1, train begins moving to stop 1.
Place stop 2, train skips to stop 2.
Train will move to stop 2, it will then go to the next station in its schedule, never going to the temporary stop 1 until it gets back to that spot on the schedule.

Trains will skip what ever temporary stop it was going to when you place another. You can no longer intuitively queue stops, such as que stop 1 for the player to enter and stop 2 for the player to exit without going through more steps.

Confirmed that this still happens in 2.0.20. To be clear, the manually-created, rail-entity temporary stop is still added before any permanent station in the schedule the train is currently at or pathing toward. But subsequent manual temporary stops are added after the previous one, without even deleting the first temporary stop, and the train only drives to the most recent temporary stop before going to the next permanent stop in the schedule. So the schedule becomes cluttered with temporary stops that were never travelled to that it will visit after the schedule loops to the beginning again.
