G'day Saint Claire,
I am the developer of Rugby League Legends. There is a bug that was introduced in the current version for older devices (iPhone3G, iPod touch 2nd Gen) that means there are no players on the field. Pretty crucial part of league, I know
Good news is that a fix was submitted to Apple a few days ago, so give it about 3 or 4 more days and it should be in the App Store. Hit update and it should be sorted.
Please let me know if you have any other thoughts/issues/ideas, would love to hear them!
Cheers,
Ben
