I finish the campaing in regular level, it was all ok. But after I started playing the campaing again in veteran. So I started playing it started fine. But when I get to the part where you have collect samples of alien tissue and they explain to you that thing of the nano catalysys counter and you collect the first 100.

I saw my counter and it was -10600 how is that posible????. What do I have a negative number??

Does anyone else have this problem???

I havent finished the campaign yet but i also get negative number when it comes to weapons. More specific Scarab rifle after the Wall Street level. Other players have also encountered the negative ammo bug.
