TF2Ware has been "fixed" on Rainbow for the time being. The TL;DR, we are now hosting copies of TF2Ware on our download server until we are assured that the Steam Workshop becomes a valid host again. Our fix is a matter of automatically updating and repacking the BSP file with a series of important edits to make it work. A full report on how it works can be read here: https://www.patreon.com/posts/scg-tf2ware-156112391 (Consider joining? :3). Because this method may eventually include numerous "old copies" of a large map, please look for our updated post regarding our record of old and unused maps coming soon!
