Transient NodeNotAvailableException rebalance under kv load

I've been running a quite heavy kv workload and rebalancing kv nodes in and out (using 3.0.0). Not always, but sometimes I see an exception like:

Couchbase.NodeNotAvailableException: Cannot find a Couchbase Server node for 10.143.194.101:11210.

   at Couchbase.CouchbaseBucket.SendAsync(IOperation op, CancellationToken token, Nullable`1 timeout)

   at Couchbase.KeyValue.CouchbaseCollection.UpsertAsync[T](String id, T content, UpsertOptions options)

   at sample.Program.Main(String[] args) in /Users/michaelnitschinger/couchbase/code/dotnet/sample/Program.cs:line 19

-----------------------Context Info---------------------------

null

So it seems that the SDK is not handling a state transition when nodes come and go properly (i.e. grabbing a new config and rescheduling the op transparently). Interestingly in the case above, the IP address was not one that I actually added or removed (10.143.194.101 was steady, in this case I added 10.143.194.102 in, but I've also seen it on rebalance out).
