How do I rearrange my war base?
During preparation day, your war base will automatically rearrange to match your village layout. If you want to rearrange your war base, just rearrange your regular village. Be aware that your war base can not be rearranged after preparation day has ended,
Edit : This means your normal village is linked to War base until the prep day is over. THEN it's copied permanently.
Till then whatever changes you make in your normal village will directly result in changes into the war base.
This is where his concern comes in. What if he can't login just few hours before his base is Permanently copied. i.e just before the prep day ends.
This leaves him no choice but to make changes earlier and that resulting his base being left exposed to the farmers.
