[Gameplay] Live Bug: Strength of Ages mastery and Cinderhulk

Cinderhulk is not properly calculating bonus health from strength of ages

steps to recreate:

1. begin game with summoner spell smite, while having Strength of Ages mastery active
2. build cinderhulk
3. stack health via strength of ages once champion reaches level 18* --during personal testing of this bug I was unable to do so before minions took the enemy base. but not being level 18 to stack means that cinderhulk calculates your leveling up hp in its number, making it appear as though its counting the stacks. it is not.
4. note the cinderhulk bonus hp value at 0 stacks, 15 stacks, and 30 stacks of strength of ages.
