Issue
A script changes on disk but Studio continues showing the previous source.
Cause
The sync mapping, supported object location, file state, or active preview session is not aligned.
Fix
Confirm the script is inside the configured sync root and has a supported file mapping. Resolve pending conflicts instead of editing both copies repeatedly. Test with one small script before syncing a full project, and keep version control outside the live conflict-resolution loop.
Verify
Change a unique comment on disk, confirm it appears once in Studio, then make the reverse edit and verify disk state.
