What is happening:
When using some skills without enough mana (but the ones that doesn't use their cooldown when doing so) and then using another skill with enough mana, it activates the cooldown of the first skill.
It can even work multiple times if you use several skills without enough mana and then use a skill with enough mana.
What should be happening:
The cooldown of those skills shouldn't be activated.
Steps to reproduce the issue:
Get your mana below the cost of those skills and use them, then use another skill with enough mana.
