Hey, thanks for the report. The plan update issue in Plan mode is known, often due to a timeout in the create_plan tool.
To figure it out, please share:
- Request ID from the chat (chat menu > Copy Request ID)
- Console: Help > Toggle Developer Tools > Console (screenshot of errors)
Quick checks:
- Copy the markdown plan to a new agent window and continue there
- Run
cursor --disable-extensionsand check - Try another model (not Auto)
Similar issue: Cursor planning mode crash - fixed by copying the plan to a new chat
The team is already working on a fix. Let us know what happened.
