Installing FOMOD archive fails with "Could not find 'Required'"

[Affront7546]

System Information

Fedora 42
Limo installed via Flatpak
Game: Skyrim Special Edition (Anniversary Edition)

Error

[Error]: Could not find 'Required'

Steps to Reproduce

1. Follow the tutorial until the step to install mods
2. Download the SSE Engine Fixes
3. Drag into Limo to install
4. Select the appropriate game version
5. Popup box will display the above error message

Additional Notes

It seems like this only happens for FOMODs that contain the "Required" directory, which presumably contains files that will be installed regardless of the options that are selected during installation.
As another example of one which does this, please see powerofthree's tweaks

A FOMOD which does not show this behavior is MCM Helper. I inspected the file with 7z a archive-name.7z and verified it does not have a directory named "Required"
I was able to install MCM Helper with no issues.

I checked the link to the FOMOD spec that was linked in tutorial, and I didn't see any information about the "Required" directory convention.

It's probably this line

Line 111 in ffdb4f9

throw std::runtime_error("Could not find '" + source_file.string() + "'");
