Whatever the cause the maker should be able to put a new surface in the call unless the pot warped real bad. Timeline dependant on the maker
I broke a jimmy Shaffer pot once, not from wood movement, I fell on it. Not only did he still fix it for me he sent a loaner call 2 days later so I still had a mad hen to make it through season before he could get to the fix on mine the we swapped back.
That is what you call above and beyond service.
