Unknownreported this bug
Seems when the shader for the Gesture-magic is used, it completely breaks normal player heads [Legacy attachment omitted]
these are all from the same head and randomly switch between random ones[Legacy attachment omitted]
this clip might showcase it better
[Legacy attachment omitted] also happens with normal player skullowner heads
Completely fixed when the RP is disabled. Tested on unmodded clients with no other resourcepacks and no server plugins
