Halloween App Icon Glitch

It's not an important glitch, but I thought I would mention it. I have an iPhone 5s and when I exit the app I see the original icon and then a half second later it switches to the Halloween icon. Just a weird thing to look into for future seasonal updates

 

Happens with the IPad as well

 

Never saw it happen on my iPhone 4

 

Not seeing it. You are not playing in the mushroom patch again are you @Gangrene Beard ?

 

It's a magical place

 

He had too much salt water! He is hallucinating

 

Arrrrgh! It's on all three of my devices, 3rd Gen IPad, iPhone 5s, and 1st gen iPad mini. Like I said, it's nothing major. I just wouldn't want it to go unnoticed and be the cause of other problems.
@Sir Bugsalot @AngryBeard - could the problem just be memory?

 

The gangrene is spreading...

 

Perhaps it's time to see a doctor....nah!

 

I'd think it was something other than the app. I'm on a 5s. Never seen this happen
