@Zyldrial
your rimworld game version doesn't match to the version of the character editor. the latest character editor works with game versions >= 1.3.3067
if your game version is lower than that, you should use the external download and get there one of the older versions.
if your game version is actual and the character editor is old, then force mod update by unsub and sub again. read the date in the mod description - it should match the date on the steam description.

@VOID Thank you for the fast reply i will try as you said <3
