[GAMEPLAY] True Grit resets on leveling up

I was testing out Graves Jungle (that is going to be a thing guys) and discovered a slight bug that will almost never matter. But that small percent of cases where it does, it is completely broken. On leveling up, True Grit drops to incredibly small numbers. I do not have the exact numbers for all ranks of the ability yet, but during the game I first noticed it, leveling up caused the passive to drop to 2 Armor and Magic Resist per stack for a grand total of 8. In the next game at rank one, it was only 1 per stack. This is going to be noticeable primarily when Graves is being a dumb and jungling, or when getting ready for team fights. Nothing quite like doing a good job, building up your Armor and Magic Resist, and right before you want to start the fight you level up and completely negate your efforts.

To reproduce the issue:

1. Put at least one point in to Quickdraw
2. Get a stack of True Grit
3. Level up

To hazard a guess, leveling up is replacing current True Grit with old True Grit. The number likely changes with level for a maximum of 3 per stack.
