I just watched it again, and I noticed that the 'little guy' in the periscope view that everyone was complaining about looks to be a quick pop-up of whoever is talking to you (in this case the XO/1WO).
I also looked at the PO bunks again, and I noticed several of them just sitting around while the boat is obviously in combat. Before I comment on that I have to ask Neal: Is there a 'Battle Stations' command you might have missed. SH4 had one that put the entire crew to work. If there is one and it puts more men in the torpedo room, that would be cool.
I also looked at the helmsman they now have sitting at the forward bulkhead. More cool stuff.
