Crew transfer when submerging

[cwhit21]

Hi, I couldn't find the answer by searching or google. I recently reinstalled everything after I couldnt get gxw to work,I installed the living mod. Anyway when I submerge the crew transfers to the electric room, but always leaves behind 3 guys so the engines stop ,thus giving the notice that not enough crew. I dont remember it being a problem in my previous games. What gives? The room is staffed but it doesn't transfer them all, if there is a officer then it's not a huge problem. Is there something I'm missing this time around, is there a solution? Thanks
