After winning against the Battle Quest opponent I'm not able to finish the quest. I'm just asked to challenge the same opponent over and over again.

EDIT: Since horizon needs to battle Pock, Saper and Riscors as well I though maybe it's just the challenger thats bugged and skipped the quest, but it's the same problem with Technicant.

Same here. I've defeated Pock Saper and Riscers several times now (I double checked and it says Battle Quest on the challenge page) but then after defeating it just gives me the options to Fight this Opponent Again or Back to Challenge Page. When I go to the BQ page it doesn't show that I have defeated it and just says I am still on level 1 and need to face Pock Saper and Rischers.

I'm also having this issue.

Ditto with Buttwing Bomber.

Same here.

Battle Arena has been really wonky these past few days. Last two days, whenever you did any action, you'd get the 'game over, see results' option (even if both sides were still very much alive) and then if you clicked that, you'd get 'invalid outcome, click here to go back to last page.' (Resolved by refreshing the page every time you made an action, annoying, but it worked.) And now this. I don't know what's up, but... I can't complete my BQs now. .___.

It's working again. But I still get the Invalid Conclusion errors.

Ditto. Can now complete battle quests.

Still getting "Invalid Conclusion" on battles which last more than one round. Relevant threads: "End Battle" appearing after each turn Early game over / "invalid conclusion" in battle

I'm getting "Invalid Conclusion" as well. Also, my Water Soul Stone didn't disappear after one use like it's supposed to.
