Any way to save so as to avoid bug issues?

[GTHammer]

Alright well this has happend to me a couple of times now and I eventually had to scrub my first campaign because of it...So everything seemed great, campaign going well. I saved my game, left came back the next day and loaded up. 1. Interior of sub always now shows the glass in the gauges shattering and falling out, and damage is reported even though I show 1. No damage and 2 wasn't recieving any when I saved. I am also not under attack by anyone at the time of load. Since then I've had a couple of CTDs(I think these are related to my using the external camera as thats when i always happens.) and more vexing I've been chugging along and suddenly my sub will suffer sudden catastrophic damage, for no reason. This results ultimately in my sinking. I looked through the forums and found a little saying that you shouldn't save while submerged. Any truth to this? Should I restart a new campaign? any other advice?
