Thanks, looking forward to the fix. HOWEVER - be careful. Unless you've recovered your original .vmf, in which case disregard the rest of this.

You're using a decompiled version of your map - it's the only way to get a .vmf from a .bsp file. Decompilers are not perfect - they screw up. As such, look out for changes in geometry, like triangles becoming squares. You may want to replace the entities in your map with new entities, though it isn't necessarily needed. Be sure to test the map extensively, that all surfaces and properties of objects are exactly what they should be.

I didn't find the center area needed to be expanded, it was quite fine. Any larger and it would be near impossible for a spy to get to the other side and survive on uncloaking. Don't put the effort into that if it's too much - small maps are small maps, and gameplay quality may be lost if they are elongated.

Pros: It's a great map, I'm sure you know all the awesome things about it. However,
Cons: Because you didn't seal off the edges of the cliffs with a playerclip or some other such thing, it is possible for soldiers and demos to easily get on top of the map. I also saw engineers up there yesterday. Now, this wouldn't be a problem, but from there you are able to drop down in behind the map, and build sentries in behind the displacements of the water area, or snipe/rocket from in behind them. This is not even mentioning the griefer possibilities. Because of this exploit, this map can't stay on my favourite server (which is actually the only server I play). It's not acceptable to leave a final version of a map with such a large exploit.
Improvements: Please, Please, Please. I know you said you wouldn't release an update, but please fix this one minor problem. All you have to do is add some playerclips in the upper area. It doesn't matter than players can get up there, but the exploit of getting under the map is too much. A blanket func_nobuild covering the whole top of the map would be great, too
Notes: Please, please, please fix this.

Love it, great to see the fixes gonna have to stick it on my server, keep it up man, some of the cliffs still need sorting though from the screenies
