[1.1.0] crash on autosave - or: fun with power poles (DifficultySettings::save)

[burninghey]

my game (factorio 1.1.1, started from steam in offline mode) just crashed to desktop.
some mods, but none should influence here

what happened before:

discovered an issue with placing wooden power poles over a ghost-built bp with steel poles. the wooden power poles did not connect to the other wooden poles, but instead to the steel-ghost-ones. then i deleted the steel ghosts. deleted the faulty wooden pole too, and replaced it.

then autosave hits. no progress in saving process .....

alt-tabbed to desktop, then crash. corrupting the autosave

how to reproduce:
- load bug save
- go a bit north, build my pattern with wooden poles (see screenshot)
- wonder the connections

i could not reproduce the autosave-crash, however.

I just reproduced the autosave crash too:



This and my other bug report are connected:

viewtopic.php?f=23&t=91817&p=522643#p522643

just could reproduce the autosave crash described there. after marking an article in tipps and tricks with missing translation read, wait for autosave.
autosave does nothing but crash after some time.
