So when can we expect a nano catalyst bug fix? I expected to be able to play through the single player and get everything out of it and now I'm kinda being cheated out of an aspect of the game since i can no longer upgrade anything in the suit. Hurry up with a fix please as i will be holding off playing the game until it works again.

Same here. No point going on and not being able to upgrade.

I'm not getting nano catalyst either. It's really pretty annoying cause I just missed out on about 1400 nano catalyst atleast. It was working fine I come back from a saved game and I killed an entire area of aliens including the one that is supposed to give you 500 nano and it says i collected it but when I hit H to upgrade my suit it says zero. So I go to the next area (this is all taking place where your suppsed to sabatoge the spore conduits, looks like an underground area over run with aliens) and I snipe several aliens 1 is another that gives you 500 I killed him but by the time I got to him the nano catalyst was no longer there. I did get nano from another alien though it said 100 catalyst collected i hit H again and it shows 60 nano for my total.

I was really irritated with all the bugs in multiplayer but I was like atleast the single player game is pretty solid, other than some direct hits not registering on people I sniped. So now having the bug were I'm not collecting nano catalyst ( a pretty significant part of the game) I'm starting to think this game isn't even finished.

Here I thought I was the only one with this issue. When are is that fix coming out?!!!!!

Yep I have the same error. At least I played for some 9 hours straight and got most of the useful upgrades. Starting a new campaign and different difficulty doesn't make any changes. I'm wondering if I delete my profile if I'll loose everything I have to date.
