So, Warmind has come and gone.. yet I am still collecting resonate stems. For that last sleeper node.... It's a weekly grind, for 4 to maybe get that last 1 node.. Now I can collect them across all 3 characters but cant use them on them. I have to change to my main character and then only am I allowed to combine the stems... ?! Sometimes I am able to combine across all the characters regardless of which one collected them... Am I doing something wrong?
