Thanks Dash. This submission was a bit of an experiment, made it two weeks ago and submitted it 5:56 am, it featured around 8:20am. People have been memeing and commenting that custom template creations have been taking a long time to feature lately. I've submitted some custom template comments as memes the next day, those all featured in under an hour. Seems like custom template comment images get reviewed and approved by the mods for featuring whether you end up submitting them or not, and older custom creations might get a spot higher in the mod review queue.
