Easiest way to explain this is to look here's a few examples:
At the start of a new page we'll have full functioning ability to format text using the standard code:
This is bold and italics and
This is out-of-character commentary for play-by-post threads.
But part of the way through the 50 posts it will break and everything will have the code to make it have formatting but will just display as standard text or bold. While editing the post it functions fine and all the formatting is there, but as soon as you post it breaks.
Once you start a new page it seems to work again...however we just had it break again on one of those boards. Not a major concern, but I miss the colors to distinguish different action types.
