Unable to Export BioMorphFaces from LE2 using Squid's Experiments

[vaultsidious2025]

Describe the bug

So far any attempt to export an LE2 BioMorphFace as pskx with Squad's experiments results in an error message. I have tried Joker, Aria, and Emily Wong so far all with the same error. LE1 and LE3 BioMorphFace exports work as expected.

To Reproduce

1. Find a BioMorphFace within an LE2 database
2. Try to export it by going to Experiments --> Squid's new and exciting ways to break stuff --> Export Selected Item as PSKX/PSA

So far, attempting to export any BioMorphFace in this way has resulted in the same error.

Expected behavior

The PSKX, PSA, and CONFIG file are properly exported to the selected directory with the user given name.

Other information

Nothing to add other than my thanks, the tools you all have created are amazing and I look forward to future updates and features.

Confirmed this bug. It happens specifically when the base head on the BioMorphFace is an import rather than an export as I expected and coded for. I will fix this in a future pull request that I'm already working on (with some new features), but in the meantime, you can work around it yourself by cloning in the base head as an export and hooking that up to the base head property. This should allow you to export it successfully.

Thanks for the report.
