Vector length error at/around 45:11

[ghost]

Forgive me for not knowing proper terms; I'm still early in my compsci journey. Been trying to convert _merged.lsx to _merged.lsf for a BG3 dye mod, but it keeps kicking back this error. It mentions vector length being 4 instead of 3, but even when I rollback to older versions, it has the same exact error. I just installed... .NET 8 I think? I'm gonna try .NET 6 if I can get my hands on the installer.
