Hush's Flow "super dash" removed by a hotfix
Players found that Hush's Flow (C) could carry her much farther than normal. Riot's China-region notes listed it as a known issue ("Hush can travel farther than intended when casting Flow (C) in certain scenarios", fix expected October 30), and a hotfix around October 29 removed it. The English 13.09 patch notes do not mention the issue or the fix.
