I was too fast with clicking, my pet lost a battle, and i misclicked (wanted to open the healer in a new tab, but just opened it normally). I tried to go back to the battle, but i couldn't click on "game over" anymore, the button was there but nothing happened. Now my pet doesn't show up for fighting anymore, I can't heal her, etc. FAQ says i should be able to access the battle via the challenge page, but there is nothing, i guess bc the battle is already over...

Is there another way to properly end this fight? Or should I file a ticket? (I feel so stupid, haha :'D)

Did you check the main page for the BC? https://subeta.net/games/battle/challenge.php

That's now the way to get back into the battle and withdraw. The old procedure was to go through the stats page.

I tried, but I couldn't see anything, the page looked normal. I don't know what happened, but I checked with the Healer again, and she showed up now (didn't before), so maybe I was just impatient? Thanks for taking the time to answer btw :)
