U-Boat sinks further after reaching critical depth

[chripsch]

Hi gents,

I just rediscovered SHIII after some time of break.(GWX 3.0)

When I am crashdiving with my VII-C boat and I pass the 150m
mark I get the notice "we`re reaching critical depth" and the boat
continues to drop... Just with an emergency blow out I could save
my boat.

While when I played the last time SHIII I could dive down to 220m
with my VII-C without any problems now I feel I must stay above
150 m. If I want to dive deeper the boat continues to drop until
the hull crashes... I can`t hold a depth like 200m.

Another "nice" experience is that when I am crash diving and I hit
the ground all crew members in the bow torpedo room are dead.
I recall that this problem in the past (some years ago) didn`t exist.

Where there changes at GWX 3.0? How can I fix this issues?!

Thank you very much for your help,
Christian
