I doubt this will be fixed but... while messing around in utility.. me and my friends decided to go in shaman mode and vampire. While dancing our bodies decide to go flat on us

probably what its suppose to look like

I highly doubt your aspect ratio is meant to be that off..

It's been like this for a while
I think it will actually happen with any action (like sitting)

That's what it looks like instead of making the vampire giant. It just gets flatter the more giant shamans you stack onto it.

And yeah it will only appear with actions just like the giant will only appear for the first time with the regular shaman during an action unless you kill and revive it.
