Well this stinks. And I was on my way to continue development until Windows 10 crashed with a MULTIPLE_IRP_COMPLETE_REQUEST error, so I had to refresh my PC, keeping the in-development game of course. This isn't the first time a PC crashed on me, and won't be the last. (Finally! it wasn't the development of the game that made a PC crash!) Anyway, the PC is refreshed and I'm getting things re-installed. I'll continue development once everything is back to normal.
