Forked conversation do not retain renamed string

Type: Bug

Hello,

WHen I create a forked conversation from another forked conversation, the renaming starts to break down for every fork.

For example:
fork index change when /fork action is created. Conversation index changes when conversation continues with further prompts.
I start with fork[0]conversation[0] - I can rename this
I create fork[1]conversation[1] - I can rename this
I create fork[2]conversation[1] - I cannot rename this or buggy. Sometimes it is renamed but after a random number of minutes.
I continue fork[2]conversation[2] - I cannot rename this or buggy. Sometimes it is renamed but after a random number of minutes.
I create fork[3]conversation[2] - I cannot rename this or buggy. Sometimes it is renamed but after a random number of minutes.
fork[4]conversation[3] - I cannot rename this or buggy. Sometimes it is renamed but after a random number of minutes.

Basically everynew fork from a more than 1 fork breaks down the renaming functionality.
It seems minor, but it is *very* hard to keep track of the conversations, especially if I am going quite deep into a codebase and I find bugs along the way that I want to track/fix/test.

Please fix.
