removing non-bootstrap node with memcached bucket okay, but adding the same node results in failures

From the attached log, one will see first the removal of a node (click remove -> click rebalance), and things are generally okay.

Following that, you'll see the node added (via the config wizard, joining to node 192.168.1.200), and one configuration received, but nothing actually used yet.

Following that, you'll see the node rebalanced in with a set of assertion errors and then workload ceases.

Notably:
