Thalia's Lieutenant not giving bonus on reinforcenent

MaxMagic420

I've noticed this before, but several patches ago. I recently tried building a human deck and it still only buffs the humans the first time you cast it. When you reinforce the Lt., it still shoots the spark at your humans in play but they don't get the +2/+2.
All other abilities trigger on reinforcement. If I cast a second Tyrant of Valakut, it still deals 6 damage to all. If this was not intentional, I'm now bringing it to your attention. Thalia's Lieutenant working properly would open up a lot of possibilities for players with a weaker card pool, as there are so many common and uncommon humans. Thank you!
