Ok I don't know if it glitched or we could not find out how to do a step. We upgraded all staffs, it didn't give any of us an option to even put them in the robots, I don't know if there's a step after you upgrade them all that we missed.
We went down to where you get the staffs and the colored lights from before where you shoot the orbs up, all were white and seemed to be giving off some morse code, we were too tired to try and figure it out, although we were turning them to see if something happened and we got them to turn all red but it only lasted for like a minute. I don't know if there's something you have to do while that's red before it turns back. If I get a chance tomorrow ill write down the signals and see if I can decipher the morse code.
