P: Typo in Gravity's Rainbow?

[Edward]

p.672, Penguin Classics Deluxe, speaking of Katje:

"Once she would have been *asessing* as she laughed, speaking of edges,
deeps, profit and loss, H-hours and points of no return--she would have been
laughing *politically*, in response to a power-predicament, because there
might be nothing else to do." [bold mine]

The error is non-existent in the Penguin Classics edition (rocket schematics
cover), p. 659. What gives? Was the Deluxe Edition prepared from an earlier,
uncorrected copy? I've noticed other errors of spelling or typography in
this edition, and I regret now not having marked them down.
