So basically all I did was extract the original zip mod folder in the main rejuvenation folder for example your (Data,Saves,Graphics etc) So I basically took the zip file I downloaded then I extracted it into my Rejuvenation-13.5.0-windows folder. At first I overcomplicated it but all you need to do simply is just put the zip into this folder then extract all the contents into that exact folder without putting the zip in any specific folders JUST in the Rejuvenation-13.5.0-windows folder and that's it
