Everybody Dance 3

(GLITCHED, Offline - Multiplayer)

This is another trophy I had issues with, after completing a 5 round party I played another 5 round party, then a 10 round party and the trophy didn't pop. I then played another 5 round party and still no trophy. The trophy eventually popped in the middle of the round of my next party (making 26 party rounds in total). Having looked around the internet no-one else seems to have had this issue so all I can suggest is make sure you get at least 1 star in each round of the party (as I know I didn't for a few of them) and keep playing until the trophy does pop if you do have issues.
