Played rank for 4 hours today. All of my work was undone by the "Game Still in progress" bug.

Earlier I placed 3rd, 2nd and then had a 1st place finish then had 2 8th place finishes from not being able to enter the game due to the "Game in progress" bug, (This happens when you try to load into a game and then another screen pops up telling you that you are already in the game, you are never able to actually join until you eventually finish 8th) this bug reversed all of the LP I gained and then some.

Incredibly annoying, is there some fix? Riot seems quiet about this bug.
