So I figured out how to change the m size and I changed the container size and adjusted the postbit style to match the new size. My board isn't live yet so I just re-imported all the avatars and they are now the new size. But the default avatars are still the old size and I can't seem to figure out how to rebuild them to the new size.
Any help would be much appreciated.
Did I mention that the current avatar system is a pain?
