Thats a problem then.
I can prehost a stream Hours before they go live without issue, (stays in host until stream goes live and ends again), so why would the problem occur around going live with a blank/unclear unhost.
Perhaps you can go look at the Twitch logs of the events in question at the time stamps stated, rather than thoerising?
How else would a bot unhost? The only way to host/unhost a channel is via a chat command, except in the case of “channel has gone offline exiting host mode” which is not occuring in this case. It’s just flat dumping the host and returning the “host credit” to spend.
If you are Twitch staff it’s not helping theorising, I’ve provided sufficient information including timestamps for you to go and LOOK at whats going on?
