Skipping frames

Hello, having problems with skipping frames, animation here is activated on click, but it doesn’t seem to play right through every time it is clicked on, any ideas why this might be?

Ps - does playing two timelines at once affect the performance - could it be that the main timeline (slight rotate) playing at the same time as timeline ‘genie’ causes it to skip?
