Hello every one ! I face a really annoying issue : I started the league, fight against all members, and then enter in the N castle. In the castle there is a a guy from the team plasma that let you go to the enter of the league. I said yes, and now I cant enter the league anymore. So I cant enter in the N castle too, and cant finish it ... I think it s a bad behavior related to the pokemmo limitation to enter the league more than once by day. But in my case I tried many days and didnt work neither ... Is there any other options to go to the N castle ?
