### Where does the bug appear (feature/product)? Cursor IDE ### Describe the Bug I am constantly getting existing code blocks (like the entire contents) deleted or duplicated. See example chat below after I restore a source file and try the same prompt. ----\> Good! The file is intact. Let me carefully add the new constants: Good! Now let me add the P/Invoke declarations. First, let me find the existing SendMessage: 🛑 STOPPING IMMEDIATELY - FILE CORRUPTED Critical Issue Detected: Shared/NativeMethods.cs has been reduced to 1 line (should be ~676 lines) My last edit somehow corrupted the file. This is exactly what you warned about. 🔧 MANUAL ASSISTANCE REQUIRED Please restore Shared/NativeMethods.cs from: Git/version control (git checkout Shared/NativeMethods.cs), OR Undo in your IDE (Ctrl+Z), OR Tell me to provide the complete file content to recreate it Once the file is restored, I need you to manually add these lines: * * * I am going in circles and burning tokens! ### Steps to Reproduce I am just using iterating over my code - it is happening regularly. Manually merging the first few changes seems to allow it push on. ### Expected Behavior Not delete entire source code - at least comment it out so I can get it back quickly - or manually merge. ### Operating System Windows 10/11 ### Current Cursor Version (Menu → About Cursor → Copy) Version: 1.7.54 (user setup) VSCode Version: 1.99.3 Commit: 5c17eb2968a37f66bc6662f48d6356a100b67be0 Date: 2025-10-21T19:07:38.476Z Electron: 34.5.8 Chromium: 132.0.6834.210 Node.js: 20.19.1 V8: 13.2.152.41-electron.0 OS: Windows\_NT arm64 10.0.26100 ### For AI issues: which model did you use? I think its an editor issue - i am using claude 4.5 sonnet thinking MAX ### Additional Information I am having to repeat the same task over and over which is burning tokens and costing me $ for no result, having to roll back and start again. ### Does this stop you from using Cursor Sometimes - I can sometimes use Cursor NEW INFO… And now I am getting this error Request ID: 2ba04884-2219-43fa-8e96-797ed96b20bc {“error”:“ERROR\_OPENAI”,“details”:{“title”:“Unable to reach the model provider”,“detail”:“We’re having trouble connecting to the model provider.

Hey, thanks for the report. Sorry you’re running into this, I can see you’re losing time and tokens. This appears to be a known issue the team is investigating. A few questions to narrow it down: 1. Which Cursor feature are you using? Inline chat(`Cmd+K`), Agent, or Ask mode? 2. Does it happen when you accept AI edits, or are files corrupted before you review/accept them? 3. Can you reproduce it with a specific file size or a particular prompt pattern? Workarounds to try: - Use Timeline (File → View Timeline) to quickly restore deleted code instead of git/undo - Review AI edits in the diff view before accepting, don’t auto‑accept large changes - Break prompts into smaller, incremental changes - Temporarily switch to a different model (e.g., GPT‑4o) to see if behavior differs About the `ERROR_OPENAI` error: It’s usually temporary, try starting a fresh chat when it appears. If it persists across new chats, restart Cursor. Let me know your answers and whether the workarounds help. ---
