CO2 won't stop rising

[Nick_Brown]

Hey there, I'm new at these forums and I'm trully sorry if there is a topic about this already, but since I can't seem to locate a search fuction I'm just gonna post it here...

This has happened to me twice already, first time it lead to the end of my career and this time I decided to ask for assistence (especially since I've sunk about 40,000tons on this mission).
I've just did a mission to take some pictures of a harbour and stayed at periscope depth during my exit. Now since my batteries were nearly flat (5/100) I decided to stop there and wait for nightfall to remain unseen... which worked (barely :p).
The problem now is that even tough I'm running on the surface, my CO2 levels are still rising (they were at 64 when I surfaced and it's at 68 now)...

I've tried diving again and resurfacing but it didn't work...

Another strange thing is that my watchcrew aren't at their posts, so one might think that it's a bug... but my batteries on the other hand ARE recharging and my feul is depleting... so the game does realise that I'm on the surface...

So does anyone know what there is going on? Cause I really don't wanna end another carreer like this
