Cursor IDE
When I ask cursor to write a plan, it prints an md file with requirements. However when I ask it to make updates or add info to the plan, sometimes it’ll delete the plan and add trailing white spaces to other files randomly.
Has anyone else ran into this bug?
plan a feature. ask it to make changes. Then the prd will get corrupted and lots of extra white spaces will be added to other files.
Draft a plan. Ask it to make updates afterwards a couple of times.

Hey, thanks for the report.
This is a known issue with updates in Plan mode. The team is already working on a fix. Similar discussions:
We need debugging data:
Is this a new chat or a long conversation
2-3 Request IDs from attempts where the plan got wiped and where whitespaces appeared
Minimal repro steps and a small repo or files with before/after .md diffs
List of installed extensions and whether format-on-save is enabled
Workarounds for now:
Start a new chat and save a copy of the plan .md before edits
Apply changes through Review with manual diff approval
Check if it reproduces on a new project branch
Please share the requested info and I’ll pass it to engineering.
Here is the request id: 7d6e21c1-e6fb-4cb0-9c84-efee25db0e1b
It was a long conversation. And the plan was large too. I believe that was a big contributor.
I’m not sure if format-on-save is enabled. Where would I find that?
I managed to restore the plan and build the feature (though troubleshooting bugs rn).
