thanks ill give it a try

just rename it from "savename.tmp" to "savename.zip" and it should work.

If this is happening a lot then there is a better temporary solution than manually renaming the files; (assuming your on windows)

In your save folder make a new text Document (.txt), Inside this file type (or copy and paste)

ren *.tmp *.zip

save the file and then rename it to something.bat when double-clicked it should make all .tmp files to .zip (you may need to press f5 to see the change)

You could place this file somewhere more accessible (such as your desktop) but to do so you must change the code to:

CD /d "C:\Users\username\Documents\Endless space 2\Save Files"
ren *.tmp *.zip

change the content in the "" to your save folder location. Also double check its working fine.

I'm back, quick question how did you guys turn the tmp files into compressed zips that the game could recognize

Cool, good to know, thank you!

Should it reoccur I will be back.  

:)

Another saving issue could happen but to avoid that: Play with the 1.0.25 preview version and do not create too big games (like with 12 factions + Exceptional Galaxy size + high galaxy density + ...).
If you met this bug again, please report it to me in this thread.

Thanks! We found the issue and the fix will be deployed soon.
In the meantime, you could be able to load this save: Here NewAmp.zip

I've had a brief look through the logs;

In 1343'12'' & 1359'47' there are Exception during serialization Errors.  

Which would suggest that something is wrong with the save that was being loaded at the time, 

something to do with hero ships it looks like.

(which is what they so far always seem to be about, something for the devs to look into?)

1114'03'' Also has some [AI0] Job raised an exception errors

Something to do with the creation of time bubbles,

I suspect its unrelated but it might be something the devs what to look at.

1331'45'', 1111'04'', 1037'04'', 1032'33'' & 1003'28''. All have two lines of:

ArgumentException: The prerequisite context must contains a valid simulation object reference. Parameter name: context

All of them occur after the "Game created." Message, 

Which always has 8 warnings of The wrapper simulation object is not initialized or released. Before it.

Which happen just after "[Game] Empire#3 loaded." (I assume the save has 4 empires ? (Computer indexes start at 0 as in 0, 1, 2, 3)

These five files have quite a few warnings in them, 

I suspect the devs can give more insight on this than I can. 

But these files do have some useful information in, So hopefully a solution can be found.

Have all these past 10 games issues been caused by the same game file being loaded ? as the issue In 1343'12'' & 1359'47' Seems diffrent to that in 1331'45'', 1111'04'', 1037'04'', 1032'33'' & 1003'28''. If they are diffrent saves could you upload the other save(s)?

Arnaud3013 could you upload your diagnostics file, it can be found in

"%Documents%\Endless Space 2\Temporary Files"

there should be 10 "Diagnostics - Date @Time.html" files with the date & time of when the game launched 

culd you upload one (or more) from a game(s) where it got stuck loading the save.

PHRAETUS are you currently using the preview build (1.0.25) ?

I would suggest you try that and see if they work there.

To use the preview build;

1) Go to your steam libraryand find Endless Space 2

2) Right Click Endless Space 2 and click properties

3) Select the Betas tab

4) Using the drop down menu op into the preview(1.0.25)- beta

5) Press Ok and Steam should update Endless Space 2

6) Try open your saves in the new version and report back here with the results

If you are already on the preview build or it does not fix the issue could you also upload your diagnostics file.

Adding to the chorus.

Having the same issue today. Hasn't been an issue previously.
Save I'm trying to load is a cloud save, gets to "Connecting to Server - Launching game" & just hangs enternally until I force close the game.

Game is allowed to access the net according to my AV's Firewall (BitDefender).

There's no .tmp extension.

Really not sure what is happening.

Cloud Save

We didn't notice something in the game that could block your file while saving your game.
This issue could appear if another software tries to access to this file. The most common: your anti-virus which wants to analyze or request a permission if the game wants to overwrite this file.

Could you try to disable it before saving a game to look if that works. Else, when you click on the "Save" button (on the save screen), do an "Alt + Tab" to watch your save folder and see if a permission request window is displayed.

Arnaud3013: Thanks for your report, we will look into your save.

DaturaNet: Could you upload your save in this thread to look into it?

Colbydude1: Thanks for your save file! Apparently, when you saved your game, the game closed before finishing to save. No worry, you just need to delete ".97.tmp" from you file name and you will be able to load it (here is your save if you want to try: Zoc B1.zip). Tell me if you continue to have ".tmp" save files.

 Quick bump. 

 Same problem here.. 

 I've done steam files checking, I've checked antivirus, firewall, folder permissions ... nothing works. 

 The {starting a new game then load saved game} workaround does not work either

 This is a great 4X ... a single game can last tens of hours and hundreds of turns... we need to be able to save / load games.. I mean.. really.... cmon..
