Riot games, our favorite small indie company, is working very hard to fix things!
Sometimes you just can't work stuff out on playtests and public beta enviroments, it just happens like that sometimes and there's definately nothing that could have been done to prevent it.
Again, this is a small indie company that we're talking about here! We're even going to try again tomorrow! It's nothing that bad, not like thousands of players coordinated their time plans well around this, right?
And in the end, I'm sure riot, despite being a small indie company, will find a way to apologise for this mishap like they have so many times before.
Let's keep cool and wait it out ;)
