my star wars map!

Here is a prototype for the Kashyyyk battle from Star Wars Episode 3. There is still alot to do, like skybox, lighting, pathnodes, playerstart, pickups, plus a whole load more detail. It is being built for a CTF layout, however I am getting presistant crashings when trying to rebuild it. Luckly I managed to get it to run and played in it, so I did a few quick snapshots to show you the rough design of it.

I have been fooling around with the UT99 map editor for 5 years. Every single map I made crashed and is lost forever. So dont expect this map ever to be posted. In the past I made a Saving Private Ryan Omaha beach along with the bridge town at the end of movie. I also recreated Hadley's Hope, the compond from Aliens. All three looked awsome and played very well.

Ya, well what do you think of this attempt for a map? It is really sloppy, but what do you expect from putting it togethor in 4 hours.
If you know anything about the UnrealED, tell me how to get rid of this small leak in the map that is crashing my editor.
