[CLIENT] Unable to choose any masteries in champion select
This is the second time this has happened to me, after finishing a game I hit play again in the post game screen and join a new game. While attempting to change masteries (either in the drop-down window or the mastery screen) I get a pop-up that says "Unexpected platform error occurred". No matter what page I turn to, this pop-up appears. Even though it does change the mastery I am on in the drop-down window, when I load into game I believe I get put on the last masteries I used. I can fix this bug by restarting the client, but this would force a queue dodge (and loss of LP if ranked obviously). The first time this happened it continued for two games in a row before I restarted the client, if that's of any help.
