[0.17.79] Crash: "Failed to reserve signal in block."

[distortions864]

I don't know what happened, I wasn't online.
It is a public multiplayer server.
It is running a custom scenario script.

Link to save: https://bhmm.net/u/fact/_autosave291.zip
I was unable to upload it here on the forums, it kept failing.

Running Ubuntu 18.04.4 LTS,
AMD Ryzen 7, 32GB DDR4

I see there is something about blueprints in the log just before the crash, so it may have to do with my script deleting large blueprints.
I just added this, because players can load very large blueprints.

Can you reproduce this in the latest version?

Cannot reproduce using given save file and 0.17.79. Unless proven otherwise i will mark this as duplicate of 80964. In the other topic there were hints of player building rails without signals that at some point connected 2 blocks that were reserved by different trains.
