Random connection drops during co-op mode

[Eragoneq]

Hi,

During some of our speedrun attempts, we ran into issues with synchronizing advancements in the coop mode. Some teammates were randomly disconnected during the run, which was noted on the server side, but they didn't receive any indication. Later after a while (probably about 2 hours) even after reconnecting, they were not getting any information about the advancements, and even after the restart, it was the case.

It's hard to reason a bit more in-depth about it as I can't see any logs, but with any guidance, I could help track down the issue, as this is annoying to deal with.
