Game automatically closed on me 3 times when Gal Gryphon shows up on VR Mining Base EQ. I'm not sure if there are other mobs that may have caused this but as far as I've seen it closes once Gal Gal Gryphon lands. Currently trying a file fix for this and awaiting the next EQ. TBH, I just returned playing PSO2 after 2 years. At first I thought it was my partitioned hard drive was causing this as it has some issues of disappearing sometimes and I have to restart my Laptop. But I have confirmed after trying 3 EQs on VR Mining Base, when Gal Gryphon shows up, the game closes. If anyone can help please let me know.
