Ever since the latest hotfix, my game crashes shortly after I log in (sometimes even in the log in screen itself). After crashing, both my screens go black, then come back and I'm sent to this page. I've followed the steps there, everything is normal and the issue remains.
Really like the idea of locking stats with Riven Slivers. I would go further and allow permanent stat locking (a higher cost would be acceptable). More player agency would make the Riven experience significantly better.
