Same problem here... -_-

Just got back into the game after having a go at Crytek on the forums and this bug is how they repay me.

They must know somehow that we're complaining and hence just stop us from being able to collect nano catalyst.

I was loving the single player with no bugs and finally they 5hit in my face.

Same problem for me. I've killed over a dozen aliens, have walked over all of their bodies, and still have zero catalyst.

Hi guys,

This is a known issue that we are currently investigating. There is an older thread already discussing this point here: http://www.gamesas.com/forums/viewtopic.php?f=40&t=12925 please post there with any relevent information such as your PC spec and the copy of Crysis 2 you are using (Steam, EADM, etc.). This will help us to resolve it as soon as possible.
