Account Page Won't Load in Lightning Experience after Millau 11.2.18

So the solution to this if anyone runs into this in their switch to lightning is:
1. Setup
2. Customize
3. Accounts
4. Buttons, Links, and Actions
5. Edit “View”
6. Switch Lightning Experience Override to be “Use the Salesforce Classic Override” or I suppose you could create a lightning component.

Simple fix.
