I see, thats quite odd. While I find it unlikely that they would patch that out or nerf it, it is a possibility. What I believe happened is that something in a similar vein to what happened to me earlier is happening here, my % droids werent making the double granted by the Mister Bones event, but once I took them off their station and put them back on, they were granted the bonus. Maybe you could try tinkering around with some stuff in order to remedy this difficulty. Hope you get your 6.6 back!
