I got this recurring crash while unloading my canning pot in my base. When I load the save, it crashes again immediately with a similar crash report. Is the save beyond fixing?

So just to be clear, it now happens even if you don’t unload the canning pot, but just when you load the save? The version number should be 0.G can you confirm that as well?

If so, you can try loading it into the most recent experimental - something about the flags on the items is breaking it when it tries to unload an item, but there’s been a lot of inventory handling fixes since. Make sure to use a copy of your save just in case, don’t cut and paste the original into the new game version.

If that doesn’t work, you can upload your save along with the crash report [to the git in a new issue](https://github.com/CleverRaven/Cataclysm-DDA/issues), and that’ll guarantee eyes on it from people who can try to fix things.

To be clear, I occurred first whilst unloading, then each time I reload, it crashes immediately upon the completion of the save loading (When I could start playing the game). I confirm I am playing on 0.G stable.

I will try to open a new git issue, how do I get the savefile? I see plenty of files in the world folder, which one is the save and how should I upload it?

Zip up the folder with the world name that the problem character is in - Don’t think you can quite make it into the debug menu to get the compressed saves they like, so next best thing.

I uploaded a fixed version of your save game in a reply to the github issue. Hopefully you can get back to enjoying the game. Cheers.
