kudu: Zip deploy started failing earlier today

I’ve been using Zip Deploy from AppVeyor for some time now with successful deployments to my site earlier in the day. The last two deployments have failed and none of the files have shown up in my staging slot.

Checking the deployment at /ZipDeploy shows the following error

2018-08-31T04:28:57.9374336Z : Copying file: 'EquineExchange.Homepage.Views.dll'

The site in question is on the account with eei-debug and has the word public in the name. I’m deploying to the staging slot with auto swap enabled.

I’m not sure if it’s related but I think this issue started after .net core 2.1.3 landed on my VM.
