i know that >.> lol i was 100% serious and i even healed on it to make sure but still was darker so...just saying
note: while taking the picture i noticed the light effects were off (usual case for me) and it seems like even though the light tool is unchecked its making it turn on while the effects are off... now go try it underground and you'll see :|
another edit for the hell of it... now light effects off gives 100% light? ...making light tool useless?
