I have had this happening since the chat refreshing update. I posted about it before but I don't think I explained what is going on well enough.

Sometimes I will copy and paste my sale ads into sales chat so I don't have to retype it. But I have had issues with when I refresh my page it will randomly post my sales ad into whatever chat I have open, this means I have posted my ads to the main chat and double posted to the sales chat. I have also had this happen with more than just ads, I can copy a horse's training, for example, refresh my page and then have it post to whatever chat. As long as I click on the chat box my computer (or the game?) will post it to chat

Hopefully, someone can help me with this. It happens maybe once a month. Super annoying when I post ads to main chat
