Ok to save a replay that you couldn't do through the normal CF interface at the end of a match is as follows:
- Go to My Documents
- Go into the Crossfire folder
- Go to Replays folder
- Find a file named ReplayTemp.rtp and rename that to [Anything you want].cfr
- It will give you a warning after you hit enter to change it that you may cause the file to become unstable. Just click ok and ignore it.
- Once you rename it to a .cfr it will automatically show up in your replays section within your storage on the CF client. No need to reload the game.
