Been trying to convert some CC hairs from S4 to S3

I grabbed a Sims3 hair CC (I have trouble finding long hair on the TSR Workshop's database), cloned it using S3OC then import the file on TSR Workshop

Then I get this error box:
""Unable to cast object of type
'Package.Sims3Files.InternalRCOL.UNKRCOLItem' to type
Package.Sims3Files.InternalRCOL.GEOM'.""

I checked importing the original CC hair and it loaded property, so the problem lies somehow in S3OC and I've been getting that same error on different cloned CC that I made with S3OC as well

So now I'm wondering if I should simply import the package file, but I don't know if doing that will create a clone of the file on TSR or if it would use the same ID. Because I don't want to replace the original CC

Yes, if you import the original package into TSRW and export it again, the instance ID will change and it will not replace the original CC.

Thank you! That will certainly save me some headaches 😭 I don't know why S3OC won't work, lost too much time trying to make these cloned files work
