A few of us (thank god for Hoyt) have taken a look at the ice movement system and we made a few changes to try and prevent this kind of error from happening in the future.

It was most likely a large drop in frame rate in your game that triggered the antihack due to your player character moving quickly through levels and your device trying to load them preemptively, causing a sort of catch up mechanic to occur that's built in to graal that drastically increases frames. However, there's no way to know without your account ID.
