SnowRunner has been updated to version 1.23 today by Focus Home Interactive. This patch is out for PS4 and fixes some bugs as seen in the patch notes.
The last major patch added content for Season 4. This one is mainly aimed at fixing a blocking bug in the mission “Lift off” of Phase 4 (very late game). This patch is available for PC and Epic Games Store but it will be released for Xbox One and Nintendo Switch at a later date. The PS4 version is available as of now.
