Thanks Jimbuna
I found a few glitches I thought I would point out though they might be features
Periscope Submerged: the game says that the periscope is submerged while the maneuver control panel says it is visible
Unable to Reach Coolant Pumps and/or Outer/Pressure Hull: crew members aren't able to reach certain components of the sub (especially in the November, Typhoon and Triton class sub) to repair them though it might be a feature to not be able to repair the outer hull.
