I have same issue, this is terrible, all my saves are unplayable.

Thank you for the saves. This incompatibility was not intended or expected (or we would ahve warned you in the patch notes). We're looking into the source of the problem, and your saves are very useful for that.

You can (still) switch to Endless Space 2 versions:

a) 1.4.21 or
b) 1.5.3

in betas tab. Worth a shot to play on your (old) save files.

-> right click on Endless Space 2 in Steam games list
-> properties
-> betas tab
-> choose version 1.4.21 - backup or 1.5.3 - backup

It should be noted that if you were playing on Patchpreview, 1.5.5 then you will not be able to play and if you were on patch preview 1.5.7 then staying on the preview will allow you to play the games as it does not download 1.5.8. 

Hi. As I already mentioned in the discussion on Steam I have the same issue. Therefore I want to provide a save file from my current game. I checked it several times yesterday and it definitely doesn't work.

Nakalim02.sav

I guess that I would have more files which are not working anymore, but I only checked this one. If you need more I can check others an upload them as well.

I was revert back to 1.5.3 and was finaly successfull with loading my saves

I hope that you fix it soon

Hey everybody!

We found a potential solution to the issue with the old saves, but it's still undergoing tests. In the meantime, we want to give you access to it through a beta branch:

1. Open the properties of ES2 on Steam
2. Go to the Betas Tab
3. Select PatchPreview

This will put you on version 1.5.9, which should be able to load the problematic saves.

Thanks, I just tried the 1.5.9 beta and I can load my troublesome saves!

Normally, I personally prefer to not use betas when playing games, so I had a couple of quick questions:

Does playing a beta version of a game still properly track and unlock Steam achievements?

Once the patch goes to the public version, will there be any compatibility issues with save files made while playing the beta?

Anyway, I hope this 1.5.9 patch goes live for the public version of the game soon!

There shouldn't be compatibility issues between this and when it goes live unless we find other critical problems that need fixing. I believe the achievements still work, but I am not entirely sure on that.

There are no issues with saves after the beta goes live - confirmed. 

I have not tested achievements while on beta yet but I have heard from various sources that achievements will still work on betas in Steam unless disabled by the developer so...still working, most likely. 

Empire Chronicles (how the game tracks your victories) will not be recorded while on beta builds - confirmed.

In my case ;)

This was the same for me for the longest time, but I eventually found a solution. There was a particular "End Game Summaries" file that was preventing all the others from loading. When I deleted that, my Empire Chronicles would then load.

Here's the thread where I went on and on about it. Hopefully it'll help you.

on 1.5.9 beta my saves also load without issues and can confirm achievements goes well too
