Not sure how I accomplished this but I know it’s not supposed to be the case. Energy meter acted as if it was constantly overloaded but I could still use weapons and cloak freely. Cloak would remain activated for as long as I wanted and remained active in the river sections of the map. Close to the chopper arrival my cloak then deactivated every couple of seconds. Upon completion of the match the shoulder cannon remained in cloak but the Predator did not.
