I'm trying to do my battle quests, and after every turn it tells me "game over" and replaces the normal "make your turn" button with "see results", no matter how much health I still have left. Clicking the button takes me to a page with an error message that says "invalid conclusion", which makes sense because the battle isn't actually over yet. The battle returns to normal if I go back a page from here, or if I just refresh after getting "game over" during the battle, but then on my next turn I get another early "game over" and have to keep refreshing to fix it.
"Game Over" while I still have health left:
Error message on the next page after clicking "see results" prematurely:

hohooh opponents, 'invalid conclusion' will not stop me from mulching you into a pulp. delay the inevitable.
ive just started to get this as well now.

Battling appears to be working / finishing for me correctly now, can you confirm it's still a problem for you?

It was ok for the first few levels of my BQs, but I'm getting it again.
I'm still getting it.

Still happening here, too. Every single turn.
And I just tested a regular battle against Buttwing Bomber, and it's happening there too. So it's not exclusive to BQs.

Same here. I also seem to hang on Nightshade. He has been the opponent for the last five levels. Never had that before, three times in a row was the maximum.
I'm having the "Oh No! Invalid Conclusion" box every second click in Battle Quests.
I tried to do the battle by just refreshing the page instead of hitting the button twice. It worked, but I didn't get the EXP for that battle.
Will stop doing my BQ now until this is fixed.
Just got this at level 7+

Seeking: or for csc or sP 🌸
I get this every other turn that my pet takes in every battle.
On level 11 and getting this issue. Hahaha Mechalag is even more obnoxious now and part of me finds this ironic/hilarious, oh gosh.
[edit] (I just tried turning pre-selection off to see if that would make a difference and it does not. Still having the same issue as stated in the thread.)
