| Summary | 0017329: Windows and Linux version of the game interpret the same savefile differently | ||||
| Description | I played a SBR game on my Linux system today (Xubuntu 15.04 x86_64) and made some nice progress. After I was done I saved the game, Steam uploaded the savefile into the steam cloud and I switched back to Windows. After loading said savefile in the Windows version I suddenly had ridiculous amounts of crime and pollution and a negative value for the amount of trash storage space (see attached screenshots). I verified that Steam didn't do anything to the savefile as both the original file (which still loads fine under Linux) and the file I loaded in Windows have the same md5 hash. Both screenshots are from the same game. The one with the high crime number is taken from an earlier savefile of the same game ("international_waters_include_land.save") | ||||

Are you sure that both the windows and linux versions are on the same version of the game? Can you look in the upper left corner of the main menu for the game on each, and make sure it's the same, and then make sure that the interpretation is different? My best guess is that the windows version updated and hence the difference, while the linux version was an older build. |
|
|
No, both have the same version. I actually installed that Linux version only after the last version (0.897) was released. On Windows I let Steam check the game cache, but that always comes up with one file that needs to be acquired no matter how many times I run it. No change to the outcome, though. I'll add a screenshot that I took in the incomp_testsave.save savefile on Linux, which shows the normal values. Anything I could try or any info I could provide you with? |
|
|
|
|
|
Hmm, okay. I'll see what we can do with checking that out on windows to see if there is anything unusual there. If you hit end turn, does it change anything? |
|
|
Oh! Can you run the 32bit linux version and see if it has the same issue as the windows version? |
|
|
Nope, hitting end turn multiple times has no effect, I tried that before reporting. Sure, I'll run the 32bit version, just let me reboot into Linux real quick. |
|
|
Took a bit longer as I needed to install a bunch of 32bit libraries, but the outcome is the same as with the 64bit version. Both Linux binaries load the save file just fine. |
|
|
Ah, gotcha -- well, thank you for the sleuthing! That definitely sounds like it is not a savegame issue then, per se, but rather some sort of calculation issue that is differing between OS. Which is, frankly, terrifying. ;) We'll see what we can see. |
|
|
No worries :) I'll try to start another game on Linux tomorrow and see if I can reproduce this, but now I need some sleep. |
|
|
No worries at all -- I appreciate it. :) For now I'd say just leave this alone and we'll see what we can figure out, and Keith may have some more specific questions for you. I suppose one other suggestion would be to save this same savegame as something like [savename]v2.save on your windows machine, and then see what your linux machine thinks of that. Does reading it in to the windows machine, then saving it back out without changing anything else, make it read in the same way on linux? That would be useful to know. I doubt it will make a difference, but knowing if it did would be one clue. |
|
|
Ok, then I'll wait for further instructions. Yep, the savegame stays "corrupted" when I save it to another savefile on Windows and load it under Linux (both 64bit and 32bit executables) |
|
|
Okay, very awesome. Thank you! Can you upload the corrupted one just for reference? |
|
|
|
|
|
No problem and done ("win_lin_test.save") |
|

For 0.899: * Fixed a bug where the serialization/deserialization of floating-point numbers in the save files was not using the invariant culture, and thus the saves were not cross-platform compatible (it could manifest as some numbers, like a city's stored trash, reading back as much higher than they actually were before the saves). ** Note that this does not repair old saves, there's really no clear way to do that, but what you can do is re-save the save on the originating platform (not the target platform) in the new version and it should load just fine wherever after that. Thanks :) |
