no longer can access my owned property

[Ariesigni]

I've been playing my save by myself for like 21 days and then i loaded into to my save and i no longer have access to motel or the sweatshop. now i don't know if it cause recently i have went into the same save with mt gf in multiplayer or if it is just a glitch but i sure hope that it gets fixed and it fixes my save cause i really don't want to start all over.

Not sure what would have caused this, but to fix it, go to a file browser (not a web browser) and paste:
%LocalAppData%Low\TVGS\Schedule I\Saves

OR manually navigate to:
C:\Users\<your username>\AppData\LocalLow\TVGS\Schedule I\Saves

You'll see a folder with a bunch of numbers, click that, then navigate to the affected save file. Go to the "Properties" folder, and select a property you're locked out of.

For example, you should now be in something like:
"SaveGame_2\Properties\Sweatshop"

There should be a Property.json file there. Open that in a basic text editor (notepad, notepad++) or preferably in a code editor like Visual Studio Code if you have it installed. The code editor just makes things easy to read when editing bigger files of this type, these should be fine in notepad. Just don't open them in a "rich" text editor like Microsoft Word or Wordpad or anything with formatting. The file should look like this:

{
    "DataType": "PropertyData",
    "DataVersion": 0,
    "GameVersion": "0.3.4f8",
    "PropertyCode": "sweatshop",
    "IsOwned": true,
    "SwitchStates": [
        true
    ],
    "ToggleableStates": [
        true,
        false
    ]
}

This should be pretty obvious, but if the "isOwned" line says false, change it to true, like above. That's it. If the game's already running, you don't even need to restart the whole game, just quit (without saving) and load the save file again.

You can do this for any property you're locked out of. You can also copy a location's folder from another save file, but if it's got a lot of objects there's a chance of some really weird corruption, especially if you host multiplayer.
