I've done the chop chop rush twice already (yes I'm sure I'm doing the saturday one) and the quest still isn't completed. Does it not work with the 25 stamina version, or is there some bug?

It's been known.

Just do Lily Wood 1-1.

I had this occur last two weeks, and Lilywood 1-1 took two attempts for me last week.

I guess its should be mori mori
