I am trying to progress through RoV and have gotten stuck on the mission "Ganged Up On". I just returned after 8 years away and wanted to do the RoV story line, but when I got to the previously mentioned mission, it wouldn't give me the CS or the lightsworm. After researching, it looked to be like some WotG missions were holding me back, so I completed all of Wings of the Goddess, including the Cait Sith fight and the Atomos fight. I tried to progress through Ganged Up On via checking the ??? at one of the 3 maws mentioned in the quest walkthrough, nothing happened. I tried zoing into Sandoria (S) and nothing. I've tried checking the Goblin Footprints in Batallia Downs (S) in order to rewatch the cutsceen and get the lightsworm, and nothing happens. I've checked the Ornate Door in the echos and nothing. I've asked many people in my LS's and I've tried every option presented with no results. I've scoured the internet and tried everything I could find, and nothing happens. I'm getting very frustrated considering I've been gone for so long and wanted to experience everything I've missed since I've been gone.
Any assistance would be greatly appreciated as I feel this is my last option and I don't want to quit playing again due to not being able to figure out a seemingly simple quest.
