Incorrectly displayed text when Energy-Based Champions are out of Energy

[GAMEPLAY] On Energy-Based champions whom do not have energy to cast abilities, the phrase "Not enough mana to cast that!" appears, instead of "Not enough energy to cast that!"

To reproduce:

1. Enter a game with any champion that uses energy (Akali, Kennen, Lee Sin, Shen, Zed)
2. Reduce your energy to less than the required energy cost of an ability
3. Attempt to cast the ability

The bug appeared in every case that I have attempted to reproduce:
