Assassin?s Creed Odyssey?s Patch 1.5.1 recently went live on all platforms, addressing myriad bug issues. While the patch is small in size (0.3GB on the PS4), it tackles issues across many sections of the game. Discovery Tour, the main game, Story Creator Mode, and The Fate of Atlantis DLC all received some sort of update in the 1.5.1 patch.
Check out the full list of patch notes below:

PB = PB || {};
PB.gptStandAlone = PB.gptStandAlone || {};
PB.gptAutoRefresh = PB.gptAutoRefresh || {'gptAds':[], 'gptStandAlone':[]};
admiralCookie = readAdmiralCookie();

googletag.cmd.push(function() {
var standAloneSizeMapping = googletag.sizeMapping().addSize([0, 0], []).addSize([750, 0], [[300, 250]]).addSize([980, 0], [[300, 250]]).build(); PB.gptStandAlone['ros_300x250_p_slot4_1571407433'] = googletag.defineSlot('/4403/cr/playstationlifestyle/ros', [[300, 250]], 'ros_300x250_p_slot4_1571407433') .defineSizeMapping(standAloneSizeMapping) .addService(googletag.pubads())

googletag.enableServices();
googletag.display('ros_300x250_p_slot4_1571407433');

if (admiralCookie === null || admiralCookie['val'] === 'false') {
googletag.pubads().refresh([PB.gptStandAlone['ros_300x250_p_slot4_1571407433']]);
}
