Totally... Just lost my Save game of chapter 3 on my Deck.
It seems steam cloud sync goes haywire if playing offline or something

yup that's exactly what happened to me back then... I never went back to it .. maybe I'll go back now with the steam deck .. how's the battery consumption on it with this game?

Lost save as described.

Did you try to contact the developer? Any chance for solution? :-)
I'm still w8ting for my Deck ... but this games was one of I want to replay :-(

The game uses a different savegame location launching the game from Steam PC or directly from the exe, so if I were you with a SteamDeck I'd backup PC savegame from:
C:\Program Files (x86)\Steam\userdata\<user ID>\245280\remote\MAINSAVE
or
%USERPROFILE%\Documents\My Games\UnrealEngine3\MonkeyGame\SaveData\MAINSAVE
to the new location used on the SteamDeck...

I have the same issue as the OP. And I don't use Steam Deck or something. Just the normal game. Played on Monday for some hours. Started again today, no saves, only new game possible.

Edit:

The above comment from hexaae helped also in my case. It seems that when you are online while playing the game, the steam/userdata folder is being used.

When playing offline, the documents/my games folder is being used.

Copied the mainsave from the steam folder to the documents folder and now the progress is back.

... mmh, so to keep them synced (either you start the game offline/from the exe or from Steam) a clever solution could be making a symlink dir to the dir in Steam remote dir...
Make a backup copy of your current MAINSAVE file first, then do:

1. delete "%userprofile%\Documents\My Games\UnrealEngine3\MonkeyGame\SaveData" directory
   
2. open a cmd prompt as Admin and execute this command (replace <user ID> with your Steam userid number):
   mklink /D "%userprofile%\Documents\My Games\UnrealEngine3\MonkeyGame\SaveData" "C:\Program Files (x86)\Steam\userdata\<user ID>\245280\remote"

This will create a new SaveData which actually points to the Steam "\remote" dir, hence every time the game loads/saves ...\remote\MAINSAVE or ...\SaveData\MAINSAVE it should load/save always the same file in "\remote" path only.

...And remember to force-quit the game from Steam overlay (in the upper right) if you don't want to generate a silent crash on exit every single time, sigh...

That sounds elegant. Would it suffice if I rename the local folder to e.g. "UnrealEngine33" instead of deleting it? In that case it would be easier to restore it in case something goes wrong (I never heard of mklink before).

The online/Steam launched mode uses "%userprofile%\Documents\My Games\UnrealEngine3\MonkeyGame\SaveData" so you have to use this same (virtual) path. Yes, of course you can reneame old dir (SaveData, not root UnrealEngine3 used by other old UE3 games!) or save a backup of just MAINSAVE file.
The game saves everything in MAINSAVE anyway (crypted and checksum signed file!), including input settings (sigh, INI files are ignored for 98% as I tried unsuccessfully for many hours to change horrible mouse negative acceleration through INI known UE3 vars...). A sloppy console port badly upgraded to "Premium Edition".

I hadn't played for years and today when I tried Continue it started from the beginning....
BUT The Chapter Select on the main page works so I can get back to roughly where I was!
