So on the latest version of level up (along with forge 2509) level up tries to give double ores for items it isn't registered for. Ie: nickel, platinum, etc. What results is that it's actually a LOSS in ores. However this can be fixed by adding the ores to the config.

I do however ask that this be remedied, i don't want some ores to gain the bonus and i don't want people to get PUNISHED for leveling up too much.
