inZOI CurseForge mod 5.6 Engine Migration Update Notes (29th April 2026)

If you logged into inZOI today and found half your mods disabled, don't panic. The inZOI Team has scheduled a 5.6 engine migration for CurseForge mod support running from 08:00 to 10:00 UTC on April 29, and the disruption is intentional.

During the two-hour window, CurseForge itself stays accessible, but previously installed mods may not load due to compatibility issues with the new engine. Newly installed mods can hit the same wall before the work wraps up. The team is clear that no mod data is being lost, everything is retained, but you will need to update your mods in CurseForge once the migration is complete before things go back to normal.

This is backend maintenance rather than a content drop, so there's not much to get excited about here. Still, keeping the mod infrastructure up to date matters for a game that leans heavily on creator tools, and at least the inZOI Team flagged it in advance rather than leaving players guessing. Here's everything that changed.
