i am running KY oval,and when I am involved in a crash,how do I activate an immediate replay to see if I was at fault,i try clicking 2 but can't figure what to do next
Press 2, name the replay, disconnect and go to "replays". You can't look at the replay while you're in a server unless you open another instance of LFS.
Instant replay doesn't exist in LFS. By pressing 2 you will save the replay. Then go to entry screen, press the Replays button and find the name of the replay you entered.
