The forum really doesn’t seem to like long posts at all. After a while it decides all of your linebreaks are just not needed, and there isn’t any way to put them back once it has decided your post didn’t need to have them.
After it decided I didn’t need linebreaks anymore, it decided to go bananas. I have no idea what has happened to my post over here:

This is the second post i’ve found where the forum decided linebreaks were not okay anymore, though the other did not proceed to go crazy and repeat itself over and over again in a big mess at least..
