For those who went to the Apple store to have the base tightened/reset did anyone experience the actual base getting looser? It used to creak quite a bit and although it creaks a little less now, the whole right side by my trackpad appears to be loose now. When you press down on it (MBA is on a flat table) it seems to click. I can drop by the Apple store again but I don't really have time to retransfer everything to my SSD if the MBA needs to be replaced. Any ideas?
