Why is the server so buggy? Cause they don't have authentic, official files. They have some kind of extender, a mod if you will, that makes the files from other chronicle (either H5 or GoD) simulate the classic ones. Thing is, to do this, it will need years of work and even then, it won't be perfect. For a perfect example remember interlude on privates. It was modified from C4 to interlude and it was extremely buggy for years, until it reached an acceptable state and still it wasn't perfect.
