Hey, sorry to hear that, the moves should usually be played very fast in the opening, and only up to 5–10 seconds in tactical situations, so I think you might have encountered a bug. Noctie does almost no calculation, just like a human, BTW.

I ran into the same bug after doing a pre-move FWIW. Someone else also mentioned that the bug might be related to the speed of making moves: https://news.ycombinator.com/item?id=33719934
Had the same problem as well. Actually, I wasn't able to finish a single game since it always got stuck (took more than a minute to play a move) after a while.
I'm using Chrome on Android and was only using the rate me page.
