Hello, this is my first time reporting a bug, and my first post on this forum. I'm not sure if it is just my device or if other players have this problem as well, but I wanted to share it just in case. If it helps, I have an Android 8.0.0. Well I wanted to be thorough with details, but apparently the forum didn't like how much content I had, so one time I had 2 characters with low energy, when I bought energy cooldown on one, it actually gained several bars, enough to fight again, while the other did not. Another time, I was using a different character, and she had about 2 bars of energy, I bought one energy cooldown, and then she only had 1 bar of energy. Final time, the second character again, she was completely out of energy, but when I bought 3 energy cooldowns, she then could fight again. This doesn't happen all the time, and the energy loss portion doesn't seem to happen to fighters with full energy.
