Don't rename maps!
Follow these steps:
1. Delete all cp_orange maps in both download and maps folders.
2. Download the map that's attached to this response.
3. Drag and drop it into your maps folder that's in your download folder.
4. Launch tf2 and hop on a blackwonder server that's playing on cp_orange_x3_blw.
(Directory for both map folders)
Download map folder: steam / steamapps / common / Team Fortress 2 / tf / download / maps
Normal map folder: steam / steamapps / common / Team Fortress 2 / tf / maps
Once you've done all of that, respond back to this thread and let me know how it went.
