When I reached Level 300, I saw the statistical screen for the Level up, all 6 Mana Colors were set at 50 points, I think that I selected the yellow one from 49 to 50, but I am not sure. It could have been a green one instead.
When I checked the Hero’s screen a few moments later, I noticed that the amount of Green Mana colour is 49 instead of 50.
How to replicate this bug?
Reach Level 300 with the Warlord class.
Presented evidence: Yes, with a forum post here and on Steam.
I have some evidence, when it first happened, I posted it on Steam. A video is also there.
