ARAM Play again --> custom games list bug

So for those of you who don't know, sometimes when you click play again in the post game lobby of and ARAM match, it'll stick you into the custom games list. How many more patches is it gonna be till you fix this bug? Its been in the game for so damn long, you'd think you could of fixed it by now. Drops your party if you're in one and is just a general pain the... Seriously it can't be that hard to fix, from my experience and what I've seen it doesn't happen in normals or in ranked, so why is it broken in ARAM?
