I've seen some weird bugs with the new point release. Perhaps the flying hog bug has something to do with a fix they implemented that got rid of "spawning vehicles floating in the air"...but your screenie shows they didn't help matters...only made them worse.
I've seen on several occasions that many enemies have invisible weapons and that at the limit of object culling distance there are several artifacts created and objects with any transparency look "dithered". I initially thought it was my graphic card but I didn't see these problems in the 1.4 release.
