No Socks RPG Save Corruption Fix Guide

For months, No Socks RPG players lost entire campaigns to a single load error: TypeError: this._lootData.screenX is not a function. The bug struck after long play sessions on Windows builds as early as v1.6, corrupting every save slot until the executable was replaced. Spicyfuse confirmed the fix path — upgrade to v2.4 or internal version 10+ — and hardened loot serialization in later patches.

This guide explains the error, who still risks it, how to back up saves before patching, and when a fresh start is smarter than recovery. Pair it with the Updates hub timeline and itch.io vs Steam builds if you are migrating between download sources.

What the error looks like

Players report the failure pattern consistently:

1. Game runs normally for hours with save and load working.
2. On the next load attempt, every slot fails with the same JavaScript-style error mentioning _lootData and screenX.
3. Reinstalling without updating the executable does not help — old builds simply re-break saves.
4. Starting a new save on an updated build works, proving the bug is save-format related, not hardware.

itch.io community posts from rosie2119 and others document the issue across multiple playthroughs. Spicyfuse replied that upgrading past affected versions resolves corruption for most players.

Root cause (player-facing summary)

RPG Maker MV/MZ exports serialize loot tables into save JSON. Older No Socks RPG builds referenced a screenX helper on loot objects that later refactors removed. When the load routine calls a missing function, the engine aborts and marks the slot unusable.

v2.4 and related patches reconcile _lootData fields so loads no longer invoke dead functions. This is why Spicyfuse tells affected players to grab the current full-game zip or verify Steam files instead of hunting manual JSON edits.

Step-by-step recovery

1. Back up before touching anything

Copy your entire save folder to a USB drive or cloud folder. On Windows, saves may live inside the game directory or %APPDATA% depending on which launcher you used. Keep the backup even if slots look broken — future tools might read partial data.

2. Update the executable

• Steam: Library → No Socks RPG → Properties → Installed Files → Verify integrity.
• itch.io: Download No Socks RPG v.2.4.zip (or newest listed) and replace the old folder entirely.
• Android APK: Install the latest itch.io build; do not overlay new APK over ancient v1.6 data without backup.

Confirm the title screen or readme reflects a current version before loading old slots.

3. Test load order

Load your newest slot first — it often contains the most recent valid flags. If it opens, immediately save to a new slot as a checkpoint. If every slot fails, proceed to step 4.

4. Isolate bad slots

Delete or move individual corrupted .rpgsave files rather than wiping the whole directory. Restore one slot at a time from backup if you want to experiment. Never delete your only backup copy.

5. Start fresh if needed

If no slot loads on v2.4, begin a new game on Easy Mode — see Easy Mode vs Normal — and use wiki walkthroughs to rush back to your previous chapter. The outfit checklist tool helps regain collection progress faster than memory alone.

Prevention habits

• Patch before marathon sessions or dungeon dives in 100 Floors of Despair.
• Maintain rotating backups every few story beats.
• Avoid copying saves from Normal executables into Easy Mode folders (or vice versa) without testing.
• Disable conflicting overlay software temporarily if loads fail only on one PC.

Developer statements

On itch.io, Spicyfuse noted:

• The game is complete, with updates adding content or fixes — not rewriting endings.
• Players stuck on Normal BP menus should use Easy Mode until mobile fixes land.
• Save corruption reports dropped sharply once version 10+ internal builds circulated alongside v2.4 packaging.

When to contact Spicyfuse

Reach out through itch.io comments or Steam discussions if:

• You updated to v2.4, started a brand-new save, and still see screenX errors (possible antivirus quarantine or partial install).
• Cloud sync merged an old save over a new one — disable Steam Cloud temporarily and verify local files.

Include platform, build version, and whether the error appears on new saves or only legacy slots.

Upgrading is boring work, but it beats losing twenty hours of outfit hunting because an old executable still calls ghost functions on loot data.
