So Sandstorm ran well until recently, at least a few weeks ago, I started getting crashes randomly. I tried to reinstall, and now I am getting an error installing 2017 x64 additional runtime 14.13.26020 that states: "The feature you are trying to use is on a network resource that is unavailable."
I have no idea how to fix this error; if I cancel the install the game will run but eventually crash to a UE4 crash reporter.
I've tried validating files and reinstalling again to no avail.
