Why did you copy and paste a post from the bug thread? You had already responded to the bug thread confirming you had the same issue @Hako posted, so why did you just copy and paste their same message into a new thread?

There’s no need for this. If that bug was reported once, creating a new thread won’t do anything else. Staff will look into the bug at some point.

Will I receive a warning?

For doing something wrong on the forums? No, it happens all the time. But you also won't receive a notification that the bug has been fixed, you'll have to check yourself.
