I've observed a hilarious bug while jumpjetting in Shadowcats (and I think also in an Orisis once or twice):
If you jump forwards and fly into a rock, sometimes, instead of stopping in your tracks, your mech will FLY backwards about 3-4x farther than you had originally jumped. Not so funny when you're trying to escape and get shot right back into your enemy's lap. :T
Dunno if this is MWLL or just Crysis freaking out, but there you have it. I had it happen once or twice before 0.5, but it's been a little more frequent in the latest version.
