worked ok for me.
By using the Advanced_knuckle, stoianm found that this was the only
way to control the speed at 7.5knots for all boats. So the trained crew
speed boost did not affect speed set. This way your trained crew will
increase your fuel efficiency instead. TC during this turn had to be at 1
for this to work.
The advanced knuckle is a useful command as it is one of the few that
will wait untill it is complete before moving to next command.
So that is why TC1 is used during the turn. When turn is finished there
is another speed check, then a 10sec wait before TC should goto 128.
Could it be a messege or some other factor setting your TC to 1
