So as I was writing a CS out I found what appears to be a bug within the BBCode (Maybe it's not even a bug? More a code-issue). It's probably never going to come up and not worth a fix in my opinion but I found it, thought it interesting and thought I would make it apparent anyway.
This is the actual code...
[sub][Indent]Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut Wah Wah Wah Wah Blah Blah Blah Blah Woo Woo Woo Woo Tut Tut Tut Tut[/indent][/sub]
So it seems indenting subbed text will make it stack on top of itself, or rather subbing indented text does.

This is the actual code...
