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-extensions and 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.
