Patch version 1.5 introduced a major game-crashing glitch connected with the improved water shaders. After installation of the patch, any attempt to go underwater would result in the game crashing. The solution to this is to delete all Skyrim data (Update and Game) in the Game Data Utility. This does not affect or include your save game data. Once this is done, reinstall the game data and the patch will update. The glitch is only present if, when updating, you have not yet downloaded patch 1.5.
A remastered Skyrim Special Edition
will be released on PS4 on October 28, 2016.
* Fixed a number of quest and item bugs.
* Companions will equip better weapons and armor if given to them.
