Hello!

In order for us to fully investigate this issue we need the following:

Your diagnostics logs. These are time stamped, and any time you close and relaunch the game, new ones are started. Please grab all diagnostics logs related to the session you were playing where the issue occurred. These are by default located:

o PC: \Users\[username]\Documents\Humankind\Temporary Files

o Mac: This is hidden in the Libraries folder. You will need to do an internet search to find specific steps for your OS. Once the libraries folder is revealed, they are in user/library/ application support/humankind/Temporary Files

- An output log. These can be found here:

o PC: This folder is hidden by default. You will need to reveal hidden folders (https://support.microsoft.com/en-us/windows/show-hidden-files-0320fe58-0117-fd59-6851-9b7f9840fdb2 ) then navigate to: Users\[username]\AppData\LocalLow\AMPLITUDE Studios\Humankind

o Mac: This is hidden in the Libraries folder. You will need to do an internet search to find specific steps for your OS. Once the libraries folder is revealed, they are in user/library/logs/amplitude studios/humankind

Truly sorry for the inconvenience! Currently a workaround may have been found by other community members which is to click multiple times on the "Refresh" button. Could you tell us if it helps avoiding the issue, event temporarily?

Thanks you for talking the time to send us your bug report!

I appear to be having this issue, here are the attached files asked for from a steam post on the same topic.

 Player.log

Temporary Files.zip

I had to zip the diagnostic files as the file upload would not let me put them up individually, sorry for any inconvenience

The Steam app updated this afternoon and now I can click on multiplayer without the error! Haven't loaded an actual multiplayer game with another player yet however. I restarted the game several times and there is no error now so hopefully it's resolved somehow via the Steam update. I'd be curious if the same is true for Vulfy?

Here's the files requested, thanks!

Temporary Files.rar

output log.rar

I can confirm that when the error occurs that you can go to new game -> multiplayer -> refresh until games populate. After that you can do whatever it seems. 

I had this issue while trying to host.  Was able to resolve it by rebooting.
