Critical Bug in Long ChatGPT Project Workflows – Split/Continue Chats Breaking

Is anyone else experiencing severe issues with “Continue Conversation” / split chats in long ChatGPT project conversations?

I’m working with very large ongoing production/project chats and I’m repeatedly running into the following problems:

  • “Conversation not found”
  • “No context”
  • split/continued chats becoming corrupted
  • chats visible in Desktop app but not in Browser
  • Browser/Desktop showing inconsistent states
  • some broken chats cannot even be deleted
  • deleting appears to work, but the chats remain permanently in the sidebar
  • every new split chat creates increasingly long “Teilgespräch / split conversation” naming chains
  • renaming sometimes triggers additional errors

This has now happened multiple times across different long-running project chats.

The original conversations still seem to partially exist, but the continue/split branch system appears unstable or corrupted.

I already reported this to support with screenshots and reproduction details.

Would be helpful to know:

  • are others seeing similar behavior?
  • especially in long project-based workflows?
  • Desktop app vs Browser inconsistencies?
  • undeletable ghost chats?

This currently makes long-term production workflows very difficult.
