I created and Closed a test topic: https://www.mediawiki.org/w/index.php?title=Talk:Sandbox&workflow=ru8qtvj1biok1y5b

I then clicked "reply" to the comment, which made the text-area open. I wrote something, and clicked "Preview" which worked. I clicked "Reply"[save], and received this error:

An error occurred.
The error message received was: This topic is closed for any further activities.

Instead, I suggest either:

• Remove the Reply link completely. [might be confusing]
• When the Reply link is clicked, open a message/dropdown that says "This topic is closed for any further activities".
• other?
