Two issues have been addressed and resolved in this update.

Biped Weapons

Bipedal aliens that carry weapons were still utilizing the old inventory system, so the weapons were unusable. I have updated this so those weapons can be used after they are dropped. I also prevented the bug that allowed players to take the alien weapons while they were still being held (although I am thinking about re-introducing this as a possible feature in the future).

Alien Bits

The animal type aliens have been updated too. In the past when they were killed their body parts would fling off in different directions. I am not sure what happened but that feature no longer worked. I was able to update it so that it is working again.
