Not sure, if I am asking in the correct place, but I already asked in the Sims 4 Studio forums, so I figured out that I could ask here as well?

I have been trying to convert some adult hairstyles to children (due to the lack of alpha hair for kids available online). However, sometimes, when I try to convert a hairstyle, I get this message:

Has anyone ever got such a message? If yes, how to fix this? I tried deleting the Sims 4 Studio folder in My Documents, it didn't work. I can't install the newest version either

Well when did you post at the Sims4Studio forum? Did you give them time to read your post? They are usually very good with support so I am guessing you might have become a little impatient.

I posted not a while ago, however I am posting here as well, just in case someone else is experiencing the same problem.

I think a moderator may be along in a moment to encourage you to keep the bug reports to where you got the tool.

If "someone else was experiencing the same problem", how would that help either of you? So yeah .. what Inge said. Also moving to Create > CAS because Help is for game issues.
