Many players are running into cloud sync issues with this game. Below are the main reasons this happens, and some steps you can take to fix it.\n\n---\n\n## What usually causes the error\n\n1. **Corrupted save files or cache**  \n   This is one of the biggest issues. Sometimes a save gets corrupted, or the Steam Cloud cache file that tracks your data (like `remotecache.vdf`) gets messed up, causing sync failures or preventing new data from uploading correctly.([steamcommunity.com](https://steamcommunity.com/app/2868840/discussions/0/798964766335986201/?utm_source=openai))\n\n2. **Outdated or mismatched sync states (local vs. cloud)**  \n   If you play on more than one device (PC, Steam Deck, etc.), your local save might diverge from the cloud save. Steam may not know which version to trust, and this mismatch can block syncing altogether.([steamcommunity.com](https://steamcommunity.com/app/2868840/discussions/0/839500962846517413/?utm_source=openai))\n\n3. **Too many history/run files overloading the cloud storage**  \n   Old or excessive run history files\u2014those `.run` files\u2014can fill up your cloud storage and trigger errors during sync. The game\u2019s developers have noted this as a recent source of problems.([reddit.com](https://www.reddit.com/r/slaythespire/comments/1umumcp/run_history_files_are_filling_steam_cloud_and/?utm_source=openai))\n\n4. **Save data or cloud functionality being disabled or broken**  \n   Occasionally the cloud option gets turned off (either manually or through update glitches), or Steam stops listing cloud support for the game. In some reports, devs temporarily disabled cloud saves in response to exploit abuse, which can also mess things up.([reddit.com](https://www.reddit.com/r/slaythespire/comments/1si3k8u/unable_to_sync_sts2_save_to_steam_cloud_from/?utm_source=openai))\n\n5. **Issues from playing while offline**  \n   If you start playing offline (or Steam is in \u201cOffline Mode\u201d) and then switch to another device, syncing can break\u2014especially if you haven\u2019t yet saved or uploaded recent progress while online.([steamcommunity.com](https://steamcommunity.com/app/2868840/discussions/0/798966745989823781/?utm_source=openai))\n\n---\n\n## Things to try to fix it\n\nHere\u2019s a step-by-step checklist you can follow. Make sure to back up anything you care about before making changes.\n\n| Step | What to do |\n|------|------------|\n| **1. Disable Steam Cloud for *Slay the Spire 2*** | Go to your Steam Library \u2192 right-click *Slay the Spire 2* \u2192 **Properties \u2192 General \u2192 Steam Cloud** \u2192 turn it off. This prevents Steam from forcing a sync that might be using corrupted or mismatched data.([reddit.com](https://www.reddit.com/r/slaythespire/comments/1scvhcp/steam_cloud_unable_to_sync/?utm_source=openai)) |\n| **2. Back up your save data** | Save files are in two main places:<br>\u2022 `C:\\Users\\<YourName>\\AppData\\Roaming\\SlayTheSpire2`<br>\u2022 `C:\\Program Files (x86)\\Steam\\userdata\\<YourSteamID>\\2868840\\remote`<br>Also the `.run` files that track history are often the culprit.([note.com](https://note.com/phoshigaki/n/n78568e734249?hl=en-US&utm_source=openai)) |\n| **3. Delete specific problem files** | Based on what people are reporting:<br>\u2022 Delete `remotecache.vdf` in the Steam userdata folder\u2014this seems to get rid of corrupted state flags.([steamcommunity.com](https://steamcommunity.com/app/2868840/discussions/0/806845425982324389/?utm_source=openai)) <br>\u2022 Remove or clean up old `.run` history files.([reddit.com](https://www.reddit.com/r/slaythespire/comments/1umumcp/run_history_files_are_filling_steam_cloud_and/?utm_source=openai)) |\n| **4. Restore a known good save** | If you have a backup, or if there\u2019s a `.corrupt` or `.backup` version of your save (e.g. `progress.save.corrupt`), rename it to `progress.save` after deleting the currently broken save.([steamcommunity.com](https://steamcommunity.com/app/2868840/discussions/0/798964766335986201/?utm_source=openai)) |\n| **5. Re-enable Steam Cloud** | Once things are cleaned up, turn Steam Cloud sync back on to force the game to upload the cleaned/valid local files. Usually Steam will prompt you to choose between local vs. cloud versions\u2014choose **local** to overwrite the cloud.([steamcommunity.com](https://steamcommunity.com/app/2868840/discussions/0/798964766335986201/?utm_source=openai)) |\n| **6. Use public beta (if available) or update the game** | Mega Crit has issued fixes especially around cloud sync issues in newer patches. If you can opt into a beta version, it might resolve lingering bugs.([steamdb.info](https://steamdb.info/patchnotes/22931561/?utm_source=openai)) |\n\n---\n\n## Why these sync issues are more common now\n\n- Recent patches have *focused on fixing cloud sync errors*, especially those when many history/run files are present.([steamdb.info](https://steamdb.info/patchnotes/22931561/?utm_source=openai))  \n- The devs have also fixed bugs like save files being overwritten if \u201ccloud sync\u201d was off, and duplicate run files causing weird conflicts.([gamesradar.com](https://www.gamesradar.com/games/roguelike/slay-the-spire-2-patch-adds-a-crowd-pleasing-buff-as-fans-say-one-card-just-became-busted-while-mega-crit-rolls-out-bug-fixes-galore/?utm_source=openai))  \n\n---\n\nIf you tell me whether you\u2019re using PC only, Steam Deck, or playing across multiple devices, I can help with more tailored steps. Do you want to try fixing it now, or would you like help gathering specific files/logs first?"
