I'm currently on the main quest "Release" and the side quest "I'm Cured". I'm supposed to defeat the Plague Oni in "Release" and talk to Wavebringer in "I'm Cured".
Wavebringer, however, is not spawning. My quest tracker is literally leading me to a now empty plot (I say "now empty" because I defeated the singular minion that had spawned, thinking maybe he would spawn after) in front of the entrance to the Plague Oni.
As for the Plague Oni, I can't get to him. I'm literally running into a big, black, shadowy wall that will not let me through, even though my quest tracker is pointing me that way.
My membership expires on the 27th and I literally can't progress any further in Mooshu without completing this quest.
