I increased the pitch of that as I thought that allowed the piece to blend in better with the other two parts. It also had the side effect of improving the audio quality.
By the way, I have been playing through PI again (first time in some sense, since my last playthrough was just before it was released and essentially a bugfixing run
) and ran into the player file corruption bug myself during the mission 9 loading sequence. It looks like that problem is not necessarily limited to red alert missions. The pilot got screwed up so badly that even going into the mainhall with it resulted in an immediate crash.
Until 3.6.10 is released, the best workaround for these issues is to simply make backups of your pilot files every few missions. For those who don't know, they are in the data\players\single directory; you want to backup the main pl2 file as well as the PI cs2 file for that pilot.
