Forum bug, potentially causing loss of posts

I was making a forum post which included a list, when I stumbled upon this potentially serious issue.

The correct syntax for a list in these forums is (replace braces with brackets, I don't know how to do unformatted text here or even if it is possible!)

{list}
{*} Item 1{/*}
{*} Item 2{/*}
{*} Item 3{/*}
{/list}

Which results in the following:

• Item 1
• Item 2
• Item 3

This is working as intended.

---

HOWEVER, if you mistype it as this:

{list}
{*} Item 1
{*} Item 2
{*} Item 3
{/list}

(i.e. leaving out the closed {*} tags), it results in this output:

• Item 1{newline

And any content of the post past the first item of the list is deleted. Erased. Gone. It's not just that it isn't displayed, even going back to edit the post only shows it up to the first item of the list. The rest of the post is, to my knowledge, unrecoverable.

I understand that breaking the BBcode syntax does not necessarily have to produce sensible results. But it should not result in unrecoverable loss of data.

Upon further investigation, the "{newline" string (with a bracket) breaks the forum as well. Try this:

Submit a post with:

---

This line displays fine. {newline
This line gets lost!

---

The result is that only the first line is displayed. Trying to edit the post again only gets you the first line, the second line (and all the rest of the post) is irretrievably lost.
