http://prntscr.com/orhs9z http://prntscr.com/orhuml I'm not sure of the issue but my avatar seems to be floating, going into the ground, constantly. I've looked into ways to resolve this..And my hover height is set at 50. I know that seems to be a common issue. I also try to adjust the hover height under preferences. But where it seems to fix the issue when i stand, as soon as i try to go and sit i'll be floating. Is there a standard hover height i should be set at? There are pictures to give examples.
