Failed Packaging - SavePackage.cpp

I’m assuming this is a engine error. I looked up the C++ file and it seems like the packager is having trouble with “PackageIndex” but unsure if this is fixable on my end.

Bumping this.

This is a blueprint only project. Has a good number of plugins installed. Been trying everything to package this for a few days. Deleted all the usual recommended project folders (intermediate, saved etc…).

Hopefully someone has encountered this issue and can point me in the right direction. Thank you!

I converted my project to C++ and based on the recommendation of a Discord user, attached the debugger to the cooking process so that I can see what file was causing the issue. The strange thing is that the error would show up once, one file at a time. I fix the file by deleting everything inside of it, package the game again, and get the same error but except, a different file would be the cause. It doesn’t show multiple errors for every file that is corrupted. I’m getting maps spitting out this error as well. Deleting the “offending” actor/s out of the map by trial and error, eventually does the same thing and changes the error to another file. In the case for the map, I just removed a static mesh that’s been sitting in a map untouched for the whole duration of development. (Forgot to delete it)

So, I wonder if I should conclude that this is a much deeper issue then just a variable in a blueprint I might have named incorrectly, or a function that I messed up? I don’t think this is a engine bug.
Is this salvageable at all?
