On trying to load autosave2 and 3 (the only ones that have done this so far), it gets to about 44%, then gives me an error message and a link to the Factorio_Current.log and asks if I want to copy it before closing Factorio regardless of what option I take.
When I tried to load autosave 1, though, I get this message after it goes about 44-50%:

As I'm typing this and trying to load the autosaves, it seems to switch between that internal error notice and the notice about the log; the internal error one doesn't close the game, though.
Loading the actual save file itself worked, thank goodness, but I'm really fearful of the day that even that won't work at all.
Booting up a save made at the very start of this save's campaign to use for the three achievements that require you to not use solar, laser turrets or logistics opens up just fine, so it is a problem with my laptop not being able to handle all the stuff I have in the game now?

As a slight side issue that I may ask about in a completely separate topic to keep the thread focused on the issue above, at least since I started this save file about 4-5 months ago, I've had problems with the game remembering even basic changes to the default settings. I still get the tips pop-up at the start of any game even if I ticked it to never show up again the last time I had the game open, and the autosaves always start at 2 mins. despite putting it at 10. It's more of an annoyance rather than an urgent problem as it doesn't seem to have messed anything up by itself, though.
