Fix modded save sync

Fixed a bug that allowed additional modded saves to actually sync via the Steam Cloud. This mod is not needed if you use a mod like UnifiedSavePath that redirects modded saves to vanilla saves.

Fix modular archive synchronization

✨ **Fixed a critical bug so that your modular saves can also be synced through Steam Cloud! **

🐛 Do I need this mod?

If you're not sure, the answer is probably **No**.

**You need this mod if:**

• You use mods
• **No** using mods like UnifiedSavePath
• When launching a modded game on a second device, it was found that **no** mod progress was synchronized at all.

💡 **Please note:** This mod does not affect the synchronization of original saves at all.

🔍 What is this bug?

In the original game (v0.99.1), although the modular archive will be uploaded to the Steam cloud, there is a key flag `IsRunningModded` that is set too late in the logic of downloading cloud data when the game starts. As a result, there is a high possibility that the modular archive data will not be downloaded and synchronized correctly.

⚠️ IMPORTANT WARNING: Your data will not be merged!

**No data merging process! **Local save and progress data will be **overwritten** by Steam cloud data.

Steam cloud saves the data of the computer that last launched the game.

**🚨 Please note before installation:** Before installing this mod, please launch the game once on the computer where you want to keep the save file.

💾 Make a backup

You can make a backup by copying the entire `modded` folder. If you accidentally overwrite an archive you want to keep, you can also look for the `.backup` file in this location to restore it.

**Windows Path:**

```

%APPDATA%\SlayTheSpire2\steam\\modded\

```

🔄 Use backup

**⚠️ NOTE: Please do not perform this operation if your device does not yet have the latest Steam Cloud data. **

After installing this mod, copy the backup data to the game's Steam cloud directory. The default path is as follows:

**Windows Path:**

```

C:\Program Files (x86)\Steam\userdata\\2868840\remote\modded\

```

After the operation, Steam will ask you whether to keep remote or local data. Select **Keep local data**.

⚠️ **This will overwrite your game's local data. **
