So sometimes (though it seems to not happen at all anymore since the patch and DLC) the game freezes while you're at the loading screen. My game froze and I rebooted my XBOX. I was a little annoyed to find that it had reset my customized characters to default and I had to play the last scene of each campaign again to unlock Arcee and Slipstream, but no big deal, just a little annoying. However, I noticed that my first Scout had my Leader's abilities. Notably Martyrdom and Seeker. So I played with my Scout and sure enough I got killed and dropped two mines. Here is the thing though. Not only do I get XP for killing enemies that are hit with the mines, but if they destroy the mines then I get the XP for that too. I haven't changed my Scout's abilities yet for fear that I'll lose this glitch permanently. I'm just going to keep it that way until I level cap my Scout or until they fix the bug. Has anyone else encountered beneficial glitches?
