At least i can make the 1st one but cannot upgrade it.

I found the issue in Baubles Reborn and I have created a pull request to fix it lazyMods/baubles#22

I will close this issue as the crash is not related to Packed Up.
Still, thanks for reporting the issue.

The crash appears to be caused by Baubles Reborn?, not by Packed Up. I can run Packed Up and upgrade the backpacks just fine without Baubles Reborn? installed.
