I'm getting some crashes off the English coast with no warning. Did a clean install, followed the instructions, was even able to run a full patrol with no issues, and this is my second patrol.
Steam, latest version, no custom mods, etc.
Here is a link to the save file. To replicate it, I just have to wait a few minutes / turn on time compression and bam, crash to desktop.
