Description of the problem you are experiencing : Arena lag or overcalculating. Not a first or last time this happens. Sometimes its impossible to interrupt, sometimes its impossible to cast mystery because apparently round has ended 10 seconds before all animations end. In this particular case, player is unable to cast either of two mysteries left after light main provides chakra with Calm mind basic attack. In other cases interrupt is simply delayed
