i did all 6 of mine solo on medium then found out i could have grouped with friends and did hard mode so now im screwed

my bad i did them on easy not medium but still i did all of mine solo then found out i could had grouped and gotten better rewards

i would like to report a bug it says if u have used up all ur rewards it wont use up ur stamina as in u can still help ur friends out with thiers without using up all ur stamina but when i tried helping my friend it wouldnt let me help cuz i didnt have enough stamina.....

in the window that opens up when u click strong approach at the bottom right it says and i quote " if the remaining reward times reach thier maximum the next fight will not consume stamina" so if i have used up all 6 of my rewards than it shouldnt use stamina
