I can't import offline code on gacha club pc, it says I imported it but it never changed my character?

Maybe it's because of the clothes color? I had the same problem and this was because of my characters pants being (grey-ish?)brown pants

Check your offline xport to see if its identical

It is probably because you are importing the same character you're already using

Try reopening gacha

Just re-make the character, then try.

Hemmm, this has happened to me before, if it does say successfully imported try clicking the X button and see if it appears after. If it doesn’t, try importing it on another preset/character, that might fix the problem. Hope this helps.
