Is it possible to make it somehow work with delayed portrait loading?
Viewing post in Improved Random Portraits v1.0
When you replaced with v1.0 (which I hope you did), did you extract it fresh, or did you just extract it over top the old one? If you didn't extract it fresh to the mods folder (delete the old one first), then yeah that still wouldn't work, the v1.0 removes a file, if you just extract over you'd change basically nothing.
