Okay I hope someone can help me here, since there's very little activity on this particular forum, I'm not ure if they'll be anyone who can. I went to the trouble of buying a 3rd controller (OCTH - Obsessive Compulsive Trophy Hunter). I had them laid out in front of me and I practiced until I could copy the following video
(they actually had 2 people - I rule).
However, I have now managed to swing between the two grimps 8 times without the middle grimp (the ball) touching the ground and yet the trophy hasn't popped. I tried redoing whilst I was online and managed to get to 7 times, but still no trophy what's going wrong? Is this trophy glitched for anyone?
