I have a sunken feeling after reading this thread this morning.
I have (nearly 'had') the intention (after watching "TheNorseCast - Gaming Done In Norway Silent 5" series and re-watching Stoianm's tutorials) to try and play this subsim on 100% reality using the Wolves of Steel mega mod.
However with the mystery of the tonnage bar not working properly I am drawn yet again to Sh3 with GWX and SHCommander (along with all the mods I've added to it) because of the career free-play.
What are my submariner comrades' views?
