Client extremely buggy after region transfer
After transferring to EUW and logging back in, I checked my in-client profile and noticed that many parts of it are bugged and corrupted with some tabs not showing at all, such as the Champions tab. My friends list is also badly glitched.
I've tried repairing my client, uninstalling and reinstalling multiple times (even made sure the whole folder was gone), and I even tried transferring back to NA, but nothing fixed the problem.
Can a Red please help me with this?
