[2020] Error with save game on cloud

Those few missing items are most likely just assets and your save should be fine. And if not, the output_log.txt (called player.log on Mac and Linux) should show us what's missing, which should help us find replacements.

The log should be from right after you've tried to load the game (leave it for 10-15 min) as it resets once the game is restarted.

Here's where to find the log depending on your operating system. To easily find the local files for the game, right click your game in the Steam library, select Properties, go to the Local Files tab and select Browse local files.

Windows
\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt

Mac OS X
Users//Library/Logs/Unity/Player.log

Linux
~/.config/unity3d/Colossal Order/Cities: Skylines/Player.log

As we can't attach files here on Steam, you will need to upload the file somewhere else. Here's a few sites you can upload it to, which do not require you to sign up first:

https://uploadfiles.io/ - free, no sign-up, can handle large log files
https://paste.ee/ - fast, no sign-up required (some log files will be too large for it though)
https://zerobin.net/ - bit clunky, but can handle huge files, no sign-up required

I have tried again on my desktop computer (different from the other time) and got no error when I click on 'subscribe all'.

My save has loaded, but I get the following error message:

Field '.Citizen.m_age' not found.

That error can also be the old Dropout. Make sure to check all your mods against the list of known broken and incompatible mods, since it sounds like the "subscribe all" grabbed some old ones at well.

Here's the list:
