Test Class Fails with certain Process Builder flow active

One of my text classes is failing, but only when I have a specific process builder flow active.  Email error is:

An error occurred at element myPreWaitDecision_myWait_myRule_8 (FlowDecision).
The flow failed to access the value for myVariable_current.Site__r.Company__r.Company_Code__c because it hasn't been set or assigned.

Here is the class:

    insert e4;

    Site__c s2 = new Site__c(Name='Test Site2');
    s2.GeoLocation__latitude__s = 000.000001;
    s2.GeoLocation__longitude__s = 000.000001;
    insert s2;

    Building__c b = new Building__c(Name = 'Test', Site__c=s2.Id);
    insert b;

    Id [] fixedSearchResults= new Id[1];
    fixedSearchResults[0] = s2.Id;
    Test.setFixedSearchResults(fixedSearchResults);

    Messaging.inboundEmail eml = new Messaging.inboundEmail();
    eml.fromAddress = 'test@test.com';
    eml.plainTextBody = 'Property-Test Site2\nType-1 Bedroom\nEmail-testname@testname.com\n02-Jan-2015';
    eml.toAddresses = new String[]{'test2@test2.com'};
    eml.fromName = 'Test Name';

    Messaging.InboundEnvelope env = new Messaging.InboundEnvelope();
    env.fromAddress = 'test@test.com';
    env.toAddress = 'test2@test2.com';

    SL_EmailParser emp = new SL_EmailParser();
    emp.handleInboundEmail(eml,env);

  }
}

Any ideas?  If I disable a process builder flow the test passes.
