I noticed some members MrSpasybo, hair, Zed0X, KrryptoBull have weird avatar proportion sizes from their original form. Originally, these avatars had rectangular shapes (signature campaign avatars), but were forced to have a fixed square shape when these users wore them. The 3 of them something have in common as "Senator".
Possible reasons are;
- they are in the same group, and having that Senator icon, but won't explain @KryptoBull's side
- they can change the avatar proportion size in settings which I don't know if it's possible, i can't see it on the settings
- a bug, maybe after using the avatar's "Personalized Picture" as it's usually a square shape
(although i don't have supporting details about this as i never used it before, and cannot try coz I'm currently in a campaign)

I only think this is a possible bug on the avatar's feature.
