As I've said multiples times on the forums 
the quest is bugged and we will fix it as soon as we can deploy the next hotfix patch. We will increase the duration of the quest so you'll still have time to complete it.

Brotherhood of Tofu quest isn't changing

I am using 1.6 game version.
occurred 10/30/2017
I am currently running into an error with the brotherhood of the tofu quest is not keep track of my ranked wins. I just won 2 ranked matches but it still says I am at 0/10 wins.
Considering it is a timed quest, I would have hoped it was running properly and keep track of my wins.

Same here, I've already won 3 or 4 ranked games and it still displays 1/10.
Same here.
I won one ranked match, number went from 0->1
I won another ranked match (enemy forfeited right at the start), i got the ranked exp but quest still stayed at 1/10.
Version 1.6.0.9007
Same here. It froze at 5 wins, and I've won at least 3 past that.
Same here. I've won 4~5 times, but it still stops at 1.
My girlfriend and I are having the same problem. :/
Same here. Looks like they do not bother with testing
Working for me just got Amalia.
it took more than 10 wins but worked in the end.
Same bug here. I keep winning but the challenge does not progress.
I also have the same problem. It stopped recording wins for me at 3 and I've won 5 more since. I keep hoping it will record after each win because I just started the game last week and I really enjoy it. I don't have many infinites so any help would be great! Please help devs!

Thanks for fixing it. It finally worked smoothly for me last night and I got Ruel!
