Me and a Friend from Austria once had some sort of... dont know if thats the correct Term, but.... we had some sort of Glitch in the Matrix, were everyone (we were 4 Players in total) was playing seperate Games all of a sudden.
it was on EotR, where we had to escort that female Umbrella-Scientist to the Helicopter. Unfortunately i dont have all the Details in my Head anymore, but after a certain Cutscene near the Apple In restaurant (i think it was the one, where this arrogant UBCS-Guy threatens this skinny guy with the glasses), my Ausie-Friend reported that i seamed to have died, and he asked me, what had killed me. I checked the Status-Screen.... and was shocked to find out, that everyone (inlcuding my Friend) was dead except of me. My friend reported the same Situation, the only Difference was, that he was alive and everyone else was dead. That makes me think, that everyone was playing their own Game apparently, as if the World we played in a few seconds ago, was splitt into 4 seperate universes. In all the Years of playing Videogames online/cooperatively, i have seen many Bugs and Glitches.... but this one was completely new to me. I laughed my Ass off, while my Ausie-Friend was raging. Though the Game was spoiled at this Point, it gave me a good Laugh and a even better Time. Thank you for bringing back the Online-Service @anyone involved, it was so worth it. :3
I had a similar issue today, playing with my Brother. We had just finished the rooftop section in Flashback, and my brother stopped moving just after exiting the storage room, in the hallway with the bulbous plant in the doorway on the left side of the screen. When he doubled back down the stairs to the first floor to check on me, his character fell to the floor. I was (apparently) completely absent from his game and he was unable to check the map, and I was playing as if he had simply died, no gameplay issues whatsoever
About 15 min later the game kicked us both and gave us the same error message: "Network Connectivity unstable, returning to room..." with the long haired zombie from Outbreak (the scenario) and then ended the game, marking us both dead and giving us a Kevin A finish portrait and treating it as if we'd played as Kevin (ie Kevin picked up X, Kevin used Y, etc). We played as Yoko/David.
I didn't play online in the early 00s so I didn't know if it was something that happened in those days or not. Sucks tho, we had almost finished it
