Elden Ring patch 1.16 is here, rolling out a number of bug fixes for Shadow of the Erdtree, although it seems it'll be up to the community to figure out most of what's actually changed.
It's admittedly a pretty tiny patch compared to some of the more elaborate balance updates we're used to, and the predictably vague descriptions of the changes make it much harder to know what's different without thoroughly delving into the game and checking any known old issues. This time around, along with "several" unnamed bug fixes, the patch notes confirm that version 1.16 has "fixed an issue where temporary boosts to player stats would remain even after closing and restarting the game." That's it, that's the whole patch.
