On the same mission, if you defeat it and start to play Delta Halo and do not reach the first checkpoint before you quit, it will not recognize that you beat the oracle mission. I had to play through it again. Which actually happened to me on Halo 2 back in 04 also…that must be a glitch that nobody every picked up on. Its happened to me three times but if I remember correctly, only on oracle to delta halo mission.
