Cyclic relationships are not replaced correctly on deserialize

To clone object structures in APEX I basically serialize and the deserialize it. It worked perfectly for this structure:
Works
with this configuration

new SObjectDataLoader.SerializeConfig()
.followChild(City__c.mdr_Country__c)
.followChild(Citizen__c.mdr_Country__c)

But when I introduced the lkp_LivesIn__c Lookup it fails to replace its value on deserialize as the value of the original City is not replaced but still points to the original record.

Fails

new SObjectDataLoader.SerializeConfig()
.followChild(City__c.mdr_Country__c)
.followChild(Citizen__c.mdr_Country__c)
.followChild(Citizen__c.lkp_LivesIn__c)

SOLUTION: Use follow() instead of followChild()

new SObjectDataLoader.SerializeConfig()
.followChild(City__c.mdr_Country__c)
.followChild(Citizen__c.mdr_Country__c)
.follow(Citizen__c.lkp_LivesIn__c)
