Confirmed for Editor v1.0.28. Your installed game must pass the Editor's build check.
2026.02 is the earlier Editor mapping label; 26457429 is the supported Steam build ID for this compatibility release. These are separate from the Editor version. Check the build status on the Editor Dashboard after attaching.
After a CC26 update: compatibility is not automatic. Some or all editing features may stop working. Writes are blocked for unverified builds.
After a new Cricket Captain release, please allow me a few days to rebuild and verify the Editor for that version.
Check Versions → Check for updates in the Editor. If it still reports an unverified build, use Report an issue to send diagnostics, or contact support.
