The top part of the image, newest version of abyss. It gets detected for me. The bottom part, an older version of abyss. Does not get detected for me. Confirmed that i can't stay on for more than 5 mins with the new abyss, 3 attempts. Probably around a dozen attempts now, on the old abyss, and i've been on for a minimum of one hour at least, and i've done things like avon MA, meaning lots of combat and moving.
I don't see it being an injection problem, since i can confirm an old abyss working. I don't see it as specific to abyss, since i can have an old abyss working. I don't think it's file details, as you can see both of the descriptions there are the same down to the file version. It's not an ini setting. I don't know specifically what the problem is, but those are the things i would feel safe arguing against, that they alone do not trigger NGS, from having played today and run several tests on them.
Moving on, there's an update tomorrow, dungeon revamp. At this point, i'd wait for that to happen, check back either thursday night or friday to see if there's been an update. May be entirely pointless to work on a fix right now, if the next update which is less than 12 hours away, renders all your work useless.
