What happened?

It will keep trying to execute this command when withReuse and withReplica are used.

Works fine when withReuse is disabled, and also works fine on initial creation of container, but fails on subsequent initializations as container exists.

Container = new MongoDbBuilder("mongo:latest") .WithReuse(true) .WithReplicaSet("rs1") .Build();
