Recently a friend seems to have issues remaining connected when we group, I got him to send me his console log.
He reports rats floating through the air, everything desyncing.
On my screen, he was downed but still running around attacking things as he was alive on his session. He soon disconnected but called it a night due to ongoing frustrations with it. Third friend had no issues and we kept playing and finished the mission as a duo.
His ping was stable at around 60-70.
Issues started happening around Patch 4.4.1.
He has no issues if solo or when hosting himself, just if he joins other peoples games (we typically use my bots so I end up hosting).
My log as host, if that can help:
console-2021-07-04-20.30.15-cf8417ad-3f71-4b81-9eac-5b4c88cabee0.log (2.0 MB)
This seems to be when he was DCd (from my logs)
