I don't know how but something bad happen to my Stadium 2 because earlier during the day I was playing in R-2, but now it seems like the R-2 is gone and that all the items I had put in the 'metal case' in Oak's lab are gone as well and I have to fight all the gym leaders in the Tower from the beginning and redo the entre Round 1. I thought it was painful just to finish Round 1 when I was a kid and it makes me want to kill myself now. Because in R-2 mode I had unlock the Doduo speed for the GB Tower so I could play Gold faster... and just the other night I had finallly managed to beat the Master Challenge Cup on R-2.
