I hope this is the right place to post this topic. I was wondering if anyone else was experiencing the same glitch that happened to me.
When I used scoop-up cyclone on a Pokemon in game, the Pokemon returned to my hand, but all the damage counters on it remained on it when it returned to my hand. I placed the Pokemon back on my bench, with all the damage counters remaining. Then I found that when trying use Acerola on that specific Pokemon in the same game, shows it as not a valid target even though it had damage counters.
