Losing context and overwriting files with stale state

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In the last week or so a very bad bug has started to surface: a certain amount of recent agent conversation context is lost, and the app ends up overwriting files with stale state.

Steps to Reproduce

I don’t know how to repro it.

I think it might happen when I submit a turn in the agent conversation and there’s an error (Cursor agent UI pops up a error saying my message was not sent to the LLM).

Expected Behavior

Context should never be lost and files should never be overwritten with stale state.

Operating System

Hey, thanks for the report. File overwrites with stale state are definitely concerning.

To help us investigate, could you please share the following:

• Request ID from when this happens:

  • Chat menu (top right) > Copy Request ID
  • Note: you’ll need to disable Privacy Mode in Settings first if it’s enabled

• Specific example:

  • Which files got overwritten, and what older state was written?
  • Screenshots of the diff would be very helpful

• Error message:

  • Screenshot of the error that appears when your message isn’t sent to the LLM

This might be related to other recent reports of Agent context issues. The team will need the Request IDs to trace what’s happening in the system.

In the meantime, please make sure you’re using version control (git) to protect against unexpected file changes.
