Plain Text Box Bug

It seems when using the plain text box to post, it no longer registers line breaks.

It isn't a problem in Edit post or New Topic. Just replys at the bottom of the page.This is a new paragraph.

Probably not the answer you're looking for, but you could always use the <p> tag at the end of your paragraphs.

So it's only a problem for replies? I've replied plain text on my iPhone without a problem, so that seems weird.
