I own over 2000 records and they definitely can warp like this. Usually when mailed incorrectly or left someplace hot like a car or mail delivery van. There are various vinyl flattening repair kits around that aim to fix issues like these. A buddy of mine has one that’s basically a pouch with the internals of an electric blanket and some heavy weights to sandwich the record between. He says it works pretty well but there’s still a slight warp even in the best cases.
