Hi Pioneers!

Here’s another attempt at fixing the connectivity issues we’ve been hearing from some players who mostly have really really big saves.

If we finally fixed these issues or if they persist please let us know over at our QA Site We’ll be glad to receive your comments either way

A reminder for people have been having issues with unexpected crashes on startup or weird behaviour with the game, in that case please try to verify your game files.

You can do this on Steam by Right Clicking the game in your Library > Properties > Local Files > Verify integrity of game files...

And on Epic by clicking on the three dots (“...”) next to the title or at the right side, depending on your selected library view > Verify

This may or may not redownload a large amount of files which might take a while depending on your internet connection or hard drive speeds so be wary of that.

If you are using mods, they might need to be updated or uninstalled after updating so please keep this in mind too.

Until next time!
