There was an error while saving snapshot.

From about month or a bit longer on most of saves i experience issue with saving game progress that end up in game error popup Like in screenshot se-save-error.png

Also when I'm in load game window, and wnat to delete on of the backup save of given game i got op-up error "Session delete failed"

How to reproduce:

1. start new custom game or custom scenario (with at least one mod it's way easier to reproduce) - easiest way is to spawn custom solar system, or one with custom planet
2. set backup save to at lease 1
3. start game
4. type /save twice in chat
5. after 2nd save command error in game pop-up will appear

What I already tried:

• full game reinstall
• graphic driver update
• directx update
• remove all mods from affected saves (with all mods files in given savegame)

First occurrence of this bug i saw when starting to play `(Workshop) AndrewmanGaming Survival 2025`. After striping it down from all mods error is still persisting. I then started new game in random start system (no mods default settings) - error was appearing but not always.

I'm also attaching latest custom save game.

Below is whole log entry for such situation (does not matter if game is modded or not) - full log in attachment:
