I was about to level up my Peacock so I played another Prize Fight. After winning I went '28 > 29' and so my character's energy go back; I decided to do do another but it gave me that low energy icon. Strange. So I check my info, and it was still at 28. I tried a Daily Event, same thing happens, I went '28 > 29' (I leveled another) and appeared like my energy went up but it is still completely spent. I even tried restarting the game and fought another match, but I can't get my levels and my energy taken away anyways. Edit: I tried it again and this time it went wonky: on the after-battle reward screen it said I was still at 28 with an empty exp bar and no level noise this time. I was worried so I check my character's info and, you know what, she is at 29 with full energy I'm assuming it might be a after-battle display error -- I don't know. My streak was still going up and my Daily Event nodes looked fine and finished after the match.
