Just wanted to report a bug I encountered a few times - when playing I like to prepare the next action so that once the animation of the first spell is done I immediately cast the second (call me efficient).
When using my wizard to cast the level 1 shock/lightning spell, she did the animation and I clicked on another spell immediately following the end of the lightning animation and instead of giving me a chance to target/use the new spell she immediately cast the same lightning spell again and turn ended (likely out of AP).
