Yes WT is supposed to sway. If it did not it would snap.
Think about a piece of wood, if you try to snap it in half when it is dry it breaks easily, now if you try that on a wet or "green" piece of wood it would bend.
The same thinking applies to steel, if it is soft it is more ductile allowing to bend, if it is a hardend piece of steel although it may be stronger it is easily cracked or broken when not supported under great stress.
The park is constantly doing "check-up" maintenance work. The same thing has recently been being done on Millennium.

I was there on the 10th and saw the basket and the crane. I also saw fresh torque check marks on the supports. My guess is it was just routine torque checking/tightening of the nuts and bolts.
Also, did you know they torque the Main Support nuts to 1650 ft lbs? that a very large number...
I did see one fresh weld at the bottom of one of the supports but it looked like a very very small weld.
