hey,everyone, I have the same issue, this is going on worldwide, you can look at other posts and see that, nothing as of right now you can do to fix it personally (on your own computer via editing something in the program files like we've had to do oh so many times), and my guess is that it'll have to be fixed via patch, since its just not registering that they are there but it is still showing that they are there in your home so it knows they are just isn't realizing they are. and btw I can vouch that this is happening all over because I and 5 others I play league with are all having it at different ip amounts and levels.
just for curiousity's sake ill explain
I am lvl 30 and stuck at 5764 says I have 6500~
friend 1 is lvl 30 stuck at 2700~ says he has 3400~
friend 2 is lvl 9 stuck at 114 says he's got 1445
3 lvl 11 stuck 320~ says 1400~
those are the ones I can remember, the other lvls are 27 and 4 same issue
I hope this helps someone, or clears some things up for you guys, and have a good day.
