Here is what I think.

In the 1.1a install, this is in the cfg/basic.cfg

;NumberOfCrew5=10
;Interval1_5=5.1
;Interval2_5=6.5
;Interval3_5=13.7
NumberOfCrew5=10
Interval1_5=30
Interval2_5=30
Interval3_5=30

This section (10 enlisted slot compartments) controls efficiency for
1. Damage Control on the Vii and iX
2. Bow Torpedoes on the II
3. Electric and Diesel Rooms on the XXI

I noticed this because I modded all compartments prior to playing 1.1a, but forgot about it until all this came up.

Interval1_x controls minimum efficiency it takes to operate the compartment.
Interval2_x has no known effect.
Interval3_x controls maximum compartment efficiency.

Basically the Interval1_5 is setting minimum efficiency impossibly high. Changing it from 30 to a 3.0, or reverting back to the commented settings, should correct this problem. Note that I have not tested this, but am basing it purely on previous observations.

Note: The commented out numbers are the settings from the original 1.0 and 1.1 JSGME installs.
