The industrial boom bonus allows you to double all of your future movement of your purple (factory/industry) token(s).Since it specifically forbids one kind of bonus and not the other, it seems reasonable to assume Ludmilla's advance can be doubled.
Ludmilla (when used) can give you a purple (factory/industry) advancement. Is that movement doubled by the industrial bonus?
You cannot double any moves received via a ? bonus, but Ludmilla is not mentioned.
Thank you in advance.
