Right when you have enough sp to cast a spell from echoes of power, press a button to cast it. No spells will be cast but you will still lose your sp(that you just gained from echoes).

Easiest way to replicate this: Out of sp -> keep spamming non-meta niacs cast and once you have enough sp to cast it, nothing happens but sp is lost.

Anyone else experiencing this? I stumbled on this problem on lvl2 sorc with acid spray and niacs. I sent bug report about this already.
