They were free when we moved, and some time after it for those who missed the moves. Now that we've been in LS for quite a long time, I believe it's going to cost for you as you should have moved it a lot earlier (if you wanted it for free).
I suggest that you make a movement appeal and see what the admins say. If you don't like the price you can always take the appeal back.

So, nope. They will cost. Thank you Oak for mentioning the rules of the movement
