Good spot @otac0n

Sorry for the delay in fixing this; I had to install Visual Studio to get the usage table regeneration working (which turned out to be unnecessary). I also had to update the NuGet API Key, and it's the middle of the night here.

I hope this resolves your issue, feel free to reopen if not.
