I was looking at my PC, and at the end were three Yoshis and a Bad Egg. Only one of them had a working picture in the PC (One of the Yoshis), so I went to one of the other Yoshis and went to change it's icon, and when I clicked Submit and went back to the PC to look at it, all three Yoshis and the Bad Egg were gone.

...What happened?

EDIT: Zekrom and Reshiram were gone too, but after a bit they came back on the next page, despite that page not even being there before (There were 151 pages, then the six adopts disappeared, then they re-appeared on page 152, which wasn't there before).

I believe I have since fixed this issue, but I'm leaving the topic open in case I didn't.

My Yoshi in my signature isn't displaying it's image/sprite. I can view it's sprite in my PC, but when it's embedded on the Forum it's completely gone.

^ My yoshi's and missingno's sprites are gone from the PC and the forum.

I have at least partially fixed the issue with Yoshi and Missingno. Tell me if you still have problems.
