[1.0.0] Crash when loading save w/o mods, no error captured

[Muppet9010]

Loading the below linked save without any of the mods it expects causes the game to crash/close. There is no error captured on screen or in the logs.

Save: https://www.dropbox.com/s/p7eyxzpmen0ju ... e.zip?dl=0

Log file attached.
No dump file is created.

Do you need the save repaired if broken but fixable?

Does the save load correctly if you sync mods to save?

[Muppet9010]

The save is fine if loaded with all the mods. So no need for any extra effort thanks.
I only tried to remove the mods so I could test another mod against the map I'm general.

Yes syncing the mods to the save is how I confirmed it worked earlier today. Technically some of the mods are sync newer than the save, but it still loads fine.
Only when no mods and the save is loaded does it crash.

So you think the game should not crash when loading a save without the necessary mods?
Or at least show some kind of error message indicating that mods are missing, either in a gui or in the log?

Yea that's exactly what it does in all other cases I've ever encountered in Factorio.
It should run a migration and remove all modded prototypes and instances and then load the map.

When Factorio ever errors it normally shows an error message and logs what went wrong. Standard error catching. So this feels like an uncaught error.

caan you upload the save? I can run it in GDB and catch a backtrace.

Does the link to the dropbox file in the original post not work for you?

Thanks for the report. You have modded spidertrons in your save and it's crashing on trying to remove them. Duplicate of basically all reports around modded spiders (such as this viewtopic.php?f=30&t=88039)

Ah, that'd be why my searching around mod removal found nothing. Thanks for heads-up.
