This bug is specific to multiplayer

Describe the issue

During a multiplayer session with a friend (in a high-ping [taking nearly a second for my actions to be seen by me], probably very low bandwidth connection - we'd suffered outright disconnects a couple times), we were both editing a station of a roller coaster (both adding/removing pieces to the front and/or back); I am unsure if the station was split at one point. In any case, we only intended for there to be 1 station and that's what it looked like it had. But once the ride was built (we both added & removed pieces during that process), it started demanding a 2nd entrance and/or exit. Test results only came in after 2 laps. The graphs (altitude/velocity/G-forces) only show a duration of 1 lap. Destroying the station and rebuilding it had no effect (we both tried). Guests will line up using the 2nd entrance, but will not enter the ride, no matter which lap the coaster trains are on. Deleting the station shows that there's still a station left (see "steps to reproduce").

I have several plugins installed, but I didn't intentionally use any of them (and to my knowledge the only ones that make changes automatically are price-related and randomizing colours of items sold by stalls). My friend, who was hosting, had no plugins installed. We didn't use any cheats or the Tile inspector; I opened the Tile inspector when the bug occurred and found only a single "Track" listed on each tile (and no Track after removing the station, despite the ride insisting there is still a station somewhere).

Steps to reproduce

1. In the attached park file, find Flying Roller Coaster 1
2. Observe that there are 2 entrances, 2 stations (in the main view) and that the Test Results show 2 sections
3. Delete its station and observe that there are still buttons for building an Entrance/Exit (though they aren't allowed to be placed anywhere)

To recreate from scratch, I suspect the multiplayer conditions I described might be relevant (i.e. high ping allowing an action to be taken from a client that seems reasonable but causes a bug by the time it's run by the host?)

Rollercoaster Heaven Glitched.zip

Start by loading the attached Rollercoaster Heaven Glitched.zip and follow the listed steps for Flying Roller Coaster 1. Investigate how multiplayer station edits are applied and how a deleted station remains represented. Done means deleting the station removes the phantom station, entrance/exit controls, and extra test section without affecting valid rides.
