i dont think they really mean to change this hover highlights dark/lighter color player name.
probably when they edit other things, 1 line from coding are messed up hence this bug occurs. it's so messed up, i need to pause for few seconds in order to swap player to correct/desire position.
anyway i think they actually do interface "improvement" with player skill like the one below when they align right the % numbers, but somehow the hover highlighted player got messed up
old version numbers are beside skill name, new version they align the numbers on right side.
quite awkward at 1st but nothing wrong/buggy here. just interface visual improvement update
