I’ve ran into this bug as well. It seems to have something to do with killing the giants too fast. If you kill all the giants before the airship stops moving, the chopper will bug out. If you wait till the airship stops moving and then kill the giants, the airship will start moving again after you kill them and go to the place where the chopper is.
So the safe way to do this dungeon is to wait till the airship stops moving before you use the reflector cannons to kill the giants.
I can confirm the bug with Simin in path 4. I’ve tried that path today and we couldn’t get her health below 50%. Every time you get to 50% she goes invisible and starts healing up. It doesn’t matter how much dps you throw at her or how fast you are with the sparks, it’s an endless cycle.
Please fix this, I really want to finish that path and it’s just impossible now!
