[Issues with the new event due to horrible loading times]

Regardless of ping and servers choice, the loading between the gates takes 15-35 minutes. Although, I get matched with a squad almost immediately after I enter this corridor. As a result, I always end up appearing on stage 3-4, and it doesn't let me get enough reputation. 

[Water Magnetic During Day and No Fish Spawns, etc]

Have you tried checking your computer's time settings? I've had the same issues when we had a clock shift in my country. Also, my squadmates saw the correct time of the day in Cetus. 

[Problems with new players?]

Had a plenty of bad interactions with new players since PoE update, mostly with Frosts blocking the objective and getting mad when asked to remove the bubble. Several outright toxic and hateful people, such as a guy who just insulted everybody on the mic nonstop for the entire mission and then decided to report the entire squad.

Though, majority of them is still nice and willing to learn. 

[Randomly teleported to Cetus from the plains]

Happened to me after the latest hotfix. Seemed to be caused by being in water. The first time this occured, I tried to fish while totally submerged in Eidolon Lake, crouching in water with only Chroma's horns sticking out. I caught a few mawfishes and then it teleported us three back to the gates, loading to get to Cetus. The last time, my friend fell into water (ocean) and we were teleported again.

[Impossible to retain progress due to constant hots migrations]

The issue persists after the hotfix. Though, I somehow managed to retain the reward once. 

[Impossible to retain progress due to constant hots migrations]

Whenever I'm returning to Cetus with a party (unless I'm the host), a host migration inevitably happens, the game shows me a loading screen and informs me that the mission was failed. This time, a host migration happened, I was sent to a solo instance and now I'm stuck between the gates with no opportunity to enter the plains or exit. Waited for 10-15 minutes and nothing changed. 

A similar thing happened with today's first sortie mission. Host migration happened when I was at extraction point waiting for the last player. "Connection with the host is lost, you will be returned to the multiplayer menu". I was prompted to reconnect with the squad, I did and was sent to the second sortie. At the end of it, neither mission was marked as "completed".

[Chat Window issues]

Also had this issue yesterday, same error code, same message. A couple of minutes later, it said it reconnected. Had no other issues that day, and I believe, I've restarted the game a couple of times after that. 

Today, the chat window is unavailable, only the loading spinner shows up on top left. Another oddity is that when I play with a host who has a different interface language (I play in English), mission results show up in that language. I already had them show up in Russian and Spanish. Also, the login screen now shows Excalibur for some reason. I don't even own one. 

I checked the network within the game settings, and the dialogue said the game detected no issues. 

I've seen a fix to this in a different topic on this forum. It said I should re-enable the Desktop service through msconfig. It was enabled all along. Disabling and re-enabling it didn't fix the issue. 

Unfortunately, the screenshot of "wrong language" part was made with a third party app, and turned out to be blacked out. I'll update this post with a screenshot of this when I make another one.
