If you are having problems with this mod I know how to fix them.
How can I fix her hair/feathers being stuck to the stage? Simple, this happened when I used the texID plugin, so don't texID Joy, If you don't know how to skip over files if you have the MassTexIDFix just type "exemptinfo" and scroll up to find out how.
How can I fix her not working on extra slots? This is because she does not have all the required files, just extract Bayo's slot 5 (c04) then place these files inside this folder and rename it as an extra slot, now that she has all files she should work over extra slots, this goes for any mod for any fighter missing some files. :)
I also ran into the same issue amphetavin had where part of the model is stuck near the middle of the stage. Not sure if it matters but I have it placed in a higher slot (c13). I just downloaded the files yesterday.
