I never encountered this issue prior to update 1.12, so I presume that the update must have had some sort of unintended consequence. The game will just randomly crash for seemingly no reason. At first I thought that it was something related to Nublar, but it's occurred on Matanceros as well. It's happened in campaign, sandbox, and challenge box, so it's not mode specific. Unfortunately, I don't know any other details or have noticed any other patterns. This is happening on PS4.
