Hello Games has detailed what's been resolved in the latest No Man's Sky patch.
In an update on the official website, the post confirmed update 1.55 has now rolled out across PC, PlayStation 4 and Xbox One, and includes fixes for a UI memory leak, a number of crashes triggered by plants, freighters, and by creating a race track in a borrowed Exocraft, as well as a number of other performance and gameplay improvements.
The patch also resolves issues where players would get stuck in The Purge and Ghost in the Machine missions, as well as a specific bug in which Sentinels would endlessly chase players unless they'd completed the final Weapon Specialist mission.
