I don’t see anything out of the ordinary with that matchmaking, looks similar to mine and I tried basically all settings.
another thing I’m trying to explore; is the project we created for example X months ago bugged? I’m moving over my ‘heavy’ devices etc to a fresh project.
I used this tycoon code before but I did quite some changes to be honest compared to previous versions. My other previous versions never had this issue (2 projects), so I’m trying to rule out if it’s my code.
Do you notice between your tycoons any correlation with date of creation? And did you change a lot in between with your code ?
Edit, just moved over my devices to fresh new project + level, nothing in the map except spawn pads, didnt change island settings from original FN template. Added the 3 devices + did some basic configuring of it (just 1 empty base basically)
Ran a private code (since couldnt use launch session)
- After 1hour, I tried to rejoin with my other acc, but it created a new session.
- I joined the party, to make sure I get in the same session, and received Network Connection Lost
I’m now going to delete the custom devices and see if I still run into the error.

You will see hightlighted as invalid

For me there is something wrong.
Its not a Ranked
If its not a ranked game should should this be True or false not invalid?
| UnrankedSet [Invalid], | |
|---|---|
| UnrankedIslands [Mnemonic=[9524-0220-6933] Version=[6]], | |
| UnrankedFallback [Invalid], |
So if its an UnrankedIsland as it has a valid code
Why is UnrankedSet [Invalid] Should Invalid be something like True/ False or Empty.
Is there a Matchmaking parameter for setting Ranked or Unranked game?
Cannot see the parameters for above in the log any where
Hey has there been found a fix for this issue?

do you recommend us to wait with posting our maps untill this is solved? Feels risky to post a 4 month project without knowing if it will flop due to a bug or not.
Hello! Im having the same issue. Has been resolved?
Having the same issue on our farm map
5234-9939-0856
Its always public lobbies that fail, private works fine
Checking for status.
Any update on this?
Based on my experience, this issue is happening on all platforms. I saw the same error while testing on Xbox and Switch. Some players from PS5 also reported the same error.
MAJOR UPDATE
@Flak we finally figured out what went wrong, this is HUGE since I found also a problem in parallel for Scene Graph.
