Blizzard bag with Max health and set health

1.when i use set max health that more then 100%(for example: Set Max Health(Event Player, 800); ) it’s change a max right but reduse current health to standart max health of hero, so if i have at that moment 2k health and add more max health it will drop it to standart health.
2.when i use Set Player Health after max health change it’s just don’t want to work, i tryied to save health of player into variable and then change max health(make more) and set player health equals to that variable(that i saved before) but nothing happen.

Blizzard please fix it! before you add action Health Pool everything worked good.
