Game Center not updating.
For example I have Jenga and have gained 15 achievements where as game center tells me I only have six. Also I have Tap Tap revenge 4, game center says that I have no achievements and actually I have nine. I think that some of the others may also be missing achievements.
How do I fix this?
I have tried switching my phone off and on and logging out and back into game center, with no luck. All my apps are up to date and I have the lastest software update.
