So much of the time, when I type a post and hit 'post reply' it tells me it's a duplicate of a post and it'll redirect me to the thread. I know it's not because I literally only just typed said post up, but the message appears however carefully I tap the button.
It doesn't really affect my board experience cause I can still type posts and respond to threads, but thought I'd mention it incase anyone else also found the same thing when they replied to a thread. It's not everytime, just some times.
