This is the editor updates released by Bungie. Although Anvil will still give you problems when patching files, the sounds portion of this file has been fixed now. You will still have problems with shape files, unless there is a fix that I am not aware of. Anvil 1.0.2 is still posted for those that have files or download files that were made with this version. As of this date I have had problems opening files created with the 1.0.2.
The latest for Forge is 1.0.4, found in another archive here.
