Found one more UBB.classic import error. However, I have a problem with this "code" even in classic, as I am not able to edit the post. Could it be the reason to why it is not imported correctly?
Attachment 1 is how it looks like in UBB.classic. Attachment 2 is how it looks like in UBB.threads beta 4. I don't know how this looked like in any previous beta.
Attachment 3 shows the complete post in classic (I removed some text). Attachment 4 show how it looks like when I try to edit it in UBB.classic.
The only thing that is not correctly imported to threads is the "code".
