Chrome hates the LL

[RiotInferno]

Chrome is notorious for Cache problems with password resets. Flush your cache, and try it.

Yeah, a flushing seemed to do the trick.
A flush / log-out / log-in worked just fine.

As a brief aside, I was able to fail once in Chrome, switch to FF, use up my log-in attempts (invoking 15m wait), switch back to Chrome and log in successfully. That seems like a bug of sorts.
