I downloaded the desktop app directly from the Ultimaker website and I received a trojan planted on my computer that I was thankfully able to remove. I don't know what's going on with this, all i wanted to do was be able to slice a complex file and not have the website error out on me.
I was running a few tests on the different AI drivatar difficulties, and I have discovered that the AIs on Coastline Sprint (not sure about other tracks I still have to test) are tied with Global Rivals' time 365. This seems completely absurd for almost anyone to do; those rivals times have hours and hours of practice in them. Expecting anyone other than the top 500 global to beat it would be a complete joke, even I am in the top 100 on a few tracks and pr stunts (without meta cars), which I think gives me a little credit and still I struggled to beat it after 15-20 attempts and eventually had to use wall taps just to pass first.
