Just recently during survival and protector co-op my partner would appear to die on my screen but would still be alive and also sometimes it would appear that he died before me but to him it's vice versa
After greater review it is a complete mess. Player location, environment conditions, enemies, even the score is different than other players game. I've been a every day if not every hour player for years and have never seen anything like it. Minor differences I notice every so often sentinels rotation reversed for example
We have not touched the game in months. What you describe though sounds like something is wrong with the deterministic approach we use for online. It shouldn't happen if both of you have the same patches installed.
It did we have review each other's replays and we play together several times a day and have for months. It seems that it is most drastic in protector. I could send you some screen shots or something if you think t would help
It is weird but my partner says there has been an issue ever since the dlc but for some reason it seems to be getting worse. I have just recently started having problems and have noticed it glitching out more often and what happen yesterday was a complete disaster. I will post what I can right now and talk to CBSAYS to see if he can post video on you tube or something like that. Thank you for being there for all of us and thank the whole crew.
