it's already happened some times since i unlocked mojo energizer power.
I see all powers off cooldown, i click mojo energizer and 1 power or 2 go cooldown again for a random amount as if it showed they were off cool down but they weren't really.
It happened on chapter 2 and 5, the 2 i have tried lately.
UPDATE: It seems to be triggered when i leave the harem window open for a while. A clear cache seem to make it go away.
