[Gameplay] Shen + Tiamat

So today I was messing around in Co-op vs ai and I found an interesting bug: Tiamat did not proc on shen. It was as though he was a ranged champion. Besides the active, his autoattacks did not do AOE. After upgrading to titanic, I found out that the titanic hydra passive indeed works, but it is concerning that the regular Tiamat doesn't. This was probably my first and last time playing hydra Shen, so I'm afraid I don't have any evidence. However, if anyone wants to try to reproduce it, you should probably go into a custom or bot game and try it out:

1. Go into game
2. Play Shen
3. Buy Tiamat
4. Metabreakers unite!
