Hopefully I'm putting this in the right place this time, thanks to Actuarily for guiding me here.
Here is the replay link, alongside the chat from my point of view.

So, I experienced a bug where the game would no longer let me attack, and I believe it has to do with how Illusion on Zoroark works.
What happens, is
between turns 10 and 11, my Chi-Yu was knocked out from full HP, while the Illusion of Chi-Yu (Zoroark) was also out, also at full HP. From my point of view, when the real Chi-Yu gets knocked out, Zoroark takes it's place. In both replays, it does not show this happening. Instead, you can see on the left side that the server thinks that both Chi-Yu and the Illusion (Zoroark) are both alive, and able to attack, but whenever I would put in an attack, the game would deny it. I tried cancelling my attacks, and that didn't work, and I didn't want to risk re-logging and losing that way, so I stayed in the match, waiting for the timer to run out. I do honestly hope this is a bug/glitch, and that my opponent didn't know about it, as otherwise I would have to believe they are using a cheating device of some kind to cause this weird situation. I do not know if this glitch/bug only applies to Chi-Yu, if it is even recreatable, or if it applies to all Pokemon. I don't intend harm or foul, so I'm just hoping this was a bug that can be fixed, especially since it locks players from playing entirely. Thank you for the help in advance!
BUG STATUS: NEEDS MORE INFO, particularly how to reproduce consistently. There have been similar reports in the past with Metronome battles (DaWoblefet)
