so I cant seem to report a bug in-game and this seams like the most likely place to get dev eyes cast on it so here we go.

on live combat brute, the 6th innate ability from legendary dreadnought does not apply its bonuses when using "Action boost: unmovable" and "Action boost: thick skin" (4th and 5th innate abilities).

tested on a ship training dummy when it was in helpless state.
