Infinite Loading Loop on Long Conversation (2+ Months of Lore / High Context)

[mattkyalo11-sketch]

Issue Description:Context:I have a single conversation session that I have been active in for over two months. It contains an extensive amount of roleplay data and world-building (hundreds of thousands of words).
The Problem:When I try to open this specific chat from my history, the interface enters an infinite loading state (the spinning wheel/loading bar never finishes). The page becomes unresponsive, and I cannot scroll or export the text.
Steps Taken:Cleared browser cache and cookies.Tried accessing via different browsers (Chrome, Firefox, Safari).Tried accessing via mobile device.The issue persists only on this specific long-running thread; new chats load fine.Request:Is there a way to retrieve the raw text or a JSON export of this specific session? I have 2 months of creative work trapped in this thread andcannot lose the data.

We hit this exact issue at Reallytics.ai with our RAG pipeline when handling long conversations - turns out it's a known limitation in the LangChain library used by FastChat. The problem's rooted in how it handles context window sizes; when you have hundreds of thousands of words, it blows past the default limits. I've seen this cause infinite loading loops too. You can try modifying the max_tokens parameter in your Conversation class, like this:

conversation = Conversation(max_tokens=2048*4)  # bump up the limit

We've had to implement a similar fix in our production code, using a combination of truncation and context summarization to keep things responsive. In our case, we were dealing with ~10K concurrent users with long chat histories, so we had to get creative with our context management.
