Non je ne croit pas, j'ai trouver ça sur un forum, mais je comprend pas tout:
I had this problem but I managed today, it seems it changed since last update, now you must not change modes.
1st try I did went responsible>power on 1st wave and did only power till I killed Mysterio, didnt work.
2nd try, from start (1st wave) I did only power movement and it counted.
So you cant change responsible>power for all the waves on Mysterio, and since Spider man starts with power, only use Power skills. 😰
