I can’t remember the name of it it’s a scootaloo story or she feels rainbow – is ignoring her and she goes for a walk in a storm and gets lost and the main six and Crusaders have to find her

I think it is this one

Unfortunately that’s not the story I was looking for the story I’m thinking about just involves the main six the CMC and a brief appearance by Big Mac Rainbow Dash get struck by lightning and brakes wing but still tries to find scootaloo by using one wing and a cloud to float a round it’s kind of an adventure story

She’s angry with rainbow because rainbow had been skipping out of flying practice but she was getting ready for a major storm

I could not find something what you want then. Sorry, wish you luck finding it though.
