Update to 11.1 - World crashes on load (AE2)

[velvet kiln]

I have updated the pack from 10.4 to 11.1, and cannot load my save (normal mode, which I don't think would effect this crash). I am getting the following error from ae2 (crash log attached):
java.lang.NullPointerException: Cannot invoke "appeng.api.stacks.GenericStack.what()" because "this.job.finalOutput" is null

Load the world back in 10.4, cancel all autocrafts and remove anything that would automatically start a crafting job.
Then try loading the world in the new version again.

I tried, but now I'm getting the same error and can't load in

[modern dust]

OK. Try removing any and all Crafting CPUs in the world, then?
Also make sure that you can load into a new world.

Sorry, I meant that I reverted back to 10.4, but it is not letting me load in.

Could I use worldedit, or something similar, to remove the crafting cpus?

[modern dust]

Hmm. You could try that yes, I don't know the exact tool you should use for that.
Another option you could try is to load a backup from 10.4

I tried "amulet", which is like a newer version of mcedit. It deleted a bunch of other stuff too though. I was able to join the world in v11.1, after deleting some of the crafting cpus. But I ended up using a backup from 10.4, which opened fine. Cancelled crafts and it is opening fine in 11.1. Only lost a bit of progress. Any idea how I can increase the frequency of backups, from 30mins to say 15mins?

Also, how do I mark this as closed?

Right-click the post in the channel menu on the left, mouse over "Edit Tags", unckeck "Open" and check "Closed".
Thank you for asking, far too many people leave their issues open. 💀

minecraft/config/ftbbackups2.json is the config file for the mod that makes backups.
