Hi! My husband purchased me my first Classic Flap in medium, lambskin over the weekend and I didn't open it until last night. The lining on the bottom is loose, as though it wasn't glued down. I am worried that over time it will wear faster or there will be a hole at some point in the near future. I'm not particularly hard on my bags, but I want to ensure that I have this bag for a while. I tried looking for other threads, posts or blogs about this but haven't found much. Does anyone else have this issue or is this the norm now?
