Crash; non-deletable bit of rail

Version: 0.14.21 through Steam, running on macOS Sierra 10.12.1. Save data at https://dl.dropboxusercontent.com/u/220 ... o_save.zip

No mods.
Foolishly I didn't capture the log file from when this actually happened (I tried it twice more after the first crash, thereby overwriting the "factorio-previous" log), so the attached log is from a reproduction rather than the original crash. The log looks pretty similar to the original one.

Steps to reproduce: load the attached saved game, which features a train just setting off after I tried to resolve a scheduling conflict. About half a second later, the game hangs (while the train is picking up speed) with a dialog box saying "Error" with message "Unexpected error occurred". The music is still playing, and the game is still visible, but the app isn't accepting any keyboard or mouse input and there is no movement on screen.

The train which is moving in this save is just going over a section of rail which I remember earlier trying to delete: a single piece of rail which gives me a message similar to "Unable to mine this" when I try and right-click it into my inventory. It was not marked with a red cross by the destruction blueprint when I tried that way, either: I just couldn't get rid of the rail.

Let me know if I can help any more.

This worked; thank you!

Was this map created in 0.14 or one of the earlier versions of the game?
