[Gamplay] Interface Bug With Thresh

After patch 5.5 came through I played two games. The first was as Morgana and no problem was encountered. The second game however, was as Thresh with the Blood Moon skin on the Mac OS X client, and I had severe problems. The game started fine. For the first several minutes of the game, nothing appeared to be wrong at all. But after I backed and bought some health pots, mana pots, and a pink ward, I immediately experienced a large bug. Multiple things went wrong. I could no longer click on items in my inventory to move them. I could no longer click on items in the store to buy or sell them. I could no longer use hotkeys to place wards, though the ward would be selected, it just wouldn't actually place. I could not cast any abilities. And finally, if I walked within auto-attack range of minions, I would begin auto-attacking (as though I were attack moving) and was unable to stop until all nearby minions were dead. I tried to Alt+Tab out and then back in, but nothing changed. I was able to use my keyboard to type and use chat, and I was able to click on the ground to move my champion, but I could do virtually nothing else. I forced the client to quit because I could not select the menu and upon logging in and returning to the game, nothing appeared to be wrong. The bug did not reoccur during that game, and I haven't played any more games since then. This could be a bug within the game, or it might just be a glitch on my computer's end, but I have also seen other people report bugs with Thresh as well, so I think it might not hurt to look into it.
