[2.0.32] Crash hosting multiplayer (RailConnectionDirection check fails)

[BattleFluffy]

I returned from a long afk to find the game crashed.
It's unclear what caused the crash and I have no info about how to reproduce it. However, the log seems to have a nice stack trace about what went wrong.
Something to do with rails, I think?

Unfortunately I have no clue how to reproduce this problem. However, I included the savegame where this happened, in case that's useful.

Some further context. I saw this in the log file:

Code: Select all

11917.736 Popped blueprint record (player-index: 73, ID: 71)
Factorio crashed. Generating symbolized stacktrace, please wait ...

I was able to look up the name of player-index 73 and talk to them. They have told me they were copying and pasting a section of rails (with signals) at the moment of the crash. There was no saved blueprint involved.

Thanks for the report. This is now fixed for the next release.
