Well if your messages are being dropped it’s likely either an issue with your code, or you’re sending messages that that may be prevented due to Twitch’s anti-spam systems or a channels moderation policy (such as auto-mod blocking what you’re bot may be doing) as even Verified Bots still are subject to any filtering/spam-prevention on Twitch’s end.
There’s not much anyone her can help with, my advice would be to slow down how often your bot sends messages because more than once per second is very fast.
