I've been having a problem with this map recently. i downloaded the map and textures, and then my brother did the same. i then started a server, and we played on it for about an hour. we just tried to open another server to just have fun on it, and it gave my brother an error message saying his map was different than mine. then we both unsubscribed and re-subscribed, deleted from within the files, and downloaded again, then he even just plain got rid of it and tried again, but to no avail. he got the same error message over and over. any help?
