Avatar .gif not working

[Lord Ghoul]

I tested out a new avatar, didn't like it and reverted back to my old one:

Only to find that the .gif isn't working and I haven't a clue why.

It'll work as an image. It won't work as an avatar.

The dimensions of that gif are 170x170 pixels. They need to be 150x150 to work as an avatar.

Resized it to 150 and it works perfectly now.

Thanks Tef!
