Chosen Broken?

I was just playing through the total conversion Chosen [http://www.doomworld.com/idgames/index.php?id=12363]. After the part with the boat and the river, a screen appears with the word "loading". The problem is, it apparently never loads because I left it open for an hour and still nothing happened. I'm using the latest SVN of zdoom. So is Chosen broken?

I just played it a few weeks ago and had no problems with it.

I've noticed in recent versions that the snake boss' clever trailing tail is broken. Now it looks like he's continually...Launching his tail at me, for lack of a better description, although it does no damage.
