We have run into this error HUNDREDS of times. We thought with the new update it would fix itself.
I had a singleplayer world used strictly for testing for our modpack.
We updated to the latest version of Origins, and still received the following error when I attempted to load into my singleplayer test world:

Upon returning to "server list"... my singleplayer world was gone. This is the screen I returned to:

While this isn't a big issue for me, as this was simply a test world, I worry for our singleplayers who download our modpack, run into this issue only to lose any and all progress they've ever made of their world. Desperately hoping for a fix ASAP.

The following was in our changelog:

At this point I cannot open a singleplayer world, no matter what. I've tried 4 times now and I just get this error every single time.
