Unable to remake despite two players never connecting.
The Yasuo left after the 3 minute mark because it never gave us the option to remake and when we tried, it told us it was too soon. As a result, we lost the game and LP for this. This shouldn't have been a loss. I don't know if it registered the Cait and Galio as connected despite the fact that they clearly never did or what, but nonetheless I am pretty sure this is a bug. The only other explanation is that they did connect and decided they'd just afk (which they remained at 0% the entire duration of loading screen, so that seems unlikely). Regardless, something wasn't right here and I suspect a bug occurred somewhere along the way.
The guy's name I didn't cross out is a friend I queued with, so no worries about name and shaming.
