Surfacing problem
 

I recently started a new career after installing the latest TMO, RSRD, PE. I've been surfaced for a while now, but I noticed that I'm still getting CO2 build-up, and the watch isn't going on duty. Basically, the game thinks I'm still submerged even though I'm not. Do you guys have any idea what could be causing this? By the way, I noticed this problem some time after destroying a freighter.

how is your sub riding in the water,

this happened to me but i had been damaged and was floating with my stern mostly submerged but my bow clean out.

Zenkmander, you have a oxygen warning notice box in the upper right hand corner of your screen. Click it. You may have to submerge before you do, but I don't think so. End of problem.
