CohereForAI/c4ai-command · is this space saving conversation or not?

Hi, for a few months i was using this space and i noticed that sometimes my conversations stay up, or then get lost. Is this a bug or a feature? Because i can't get the hang of it. Sometimes i talk to it, and conversation will get lost maybe in 10 minutes after i started new chat. Like here i was asking for DnD ideas for Fort life, and i asked few clarifying questions and get into nitty gritty details and then my conversation just got erased. Here is how it looks like when its getting erased. If i just reload the page, all the conversation links on the left will disappear

Here is the link to my conversation that i opened in a new tab, its not there anymore

Is this a bug or a feature? If its a feature, like auto-delete, can we turn it off or could there be atleast a timer with countdown saying how much time is left untill its all erased?
