I've had two other bugs recently, one of which repeated. In the Davion Flashpoint in which you're hired to assassinate two insurgent Liao-friendly leaders, but end up making things worse, I spent the entire second scenario (I opted to spare the hostages) with my Star League-era Griffin running around as an orange ghost. It didn't affect game play, but it was a little distracting.
Twice I've had situations near the end of generic Recovery missions when half of the sound went out, mostly affecting speech with special effects largely untouched. The first time it happened the game crashed after hitting the acknowledgement that the scenario had ended successfully, and I had to re-play it, which took about 90 minutes. The second time I immediate saved the game, then re-saved after every turn, but there was no crash and the sound came back during the post-mission wrap-up. Other Recovery missions have been bug free.
