Sims 4 Patch 1.122 Triggers Mass Mod Compatibility Reset Across Community Trackers

Scarlet's Realm, SimsVIP, and ModHound all reset their mod compatibility databases to "unknown" within hours of The Sims 4's 1.122 patch dropping on March 17, 2026, leaving players with potentially hundreds of flagged mods and no immediate clarity on what's safe to run.

This kind of mass reset is the community tracker version of a fire drill. Every major patch puts third-party lists in the same position: the game has changed, no one yet knows what broke, and the responsible move is to wipe the green checkmarks until mod creators have had a chance to load up their packages and confirm nothing exploded. The 1.122 patch triggered exactly that response across all three of the community's most-relied-upon tracking services simultaneously.

What that means practically is that if you opened Scarlet's Realm or ModHound this morning expecting a clean status board, you found a sea of "unknown" flags instead. That's not the trackers failing — that's them working exactly as intended. The reset protects players from trusting outdated compatibility data after a patch that may have touched scripts, tuning files, or core game resources that mods hook into.

The verification process from here falls on individual mod creators. Each one needs to test their package against 1.122, then report back to the tracking services or update their own pages. Scarlet's Realm and SimsVIP have historically been fast at pushing verified statuses through once creator confirmations start coming in, but the first 24 to 48 hours after any major patch are always the murkiest. Smaller mods from creators who aren't actively maintaining their work may stay "unknown" indefinitely.

For anyone running a heavily modded game, the safest call right now is to pull your Mods folder out entirely and wait for the trackers to populate with confirmed statuses. Running unknown mods against a freshly patched build is how you end up with corrupted saves or a broken UI that's nearly impossible to diagnose. ModHound's flagging system makes it relatively straightforward to cross-reference your installed packages against the pending verification list once updates start rolling in.

The pace of creator verification over the next few days will determine how quickly the community gets back to a reliable picture of what's working on 1.122.
