No idea if this is the right place to mention this, but the other day when playing on the server I noticed that it still has pl_swift_final on it, the maker of the map has continued developing it and has renamed it to pl_swiftwater. There are some good improvements in it (including fixing the glitch/bug that allowed you to build on one of the roofs where it wasn't supposed to (and which usually ment me pissing off other people on the GoT server).
We can take a look @ it.. http://forums.tf2maps.net/showthread.php?t=6749 And maybe test it on a server....
Having played both I can say that the improvements are pretty good, I especially like this one: -Additional route from cave into CP2 area The end of the cave used to be one massive choke point, this little cave solves that problem.
