Coin Flip Bug - see results prior to flip

During my last match, my opponent had Ambipom with Primate Dexterity ability in play, so they got to flip after I attacked to determine if damage was applied. I noticed that before I selected my Lunatone's Moon Kinesis attack, my attack showed 0. They ended up getting heads, and I was able to pre-determine the results of those flips for the rest of the game. I was also able to influence the outcome by retreating and attacking with a different 'mon. When I saw they would get a heads (my attacked showed it would do 0 instead of 120), I could switch Pokemon and sometimes get the expected attack to show (so I could essentially flip 2 coins before the attack instead of one after the attack). Please let me know if you need more info
