stale index data?

Build 2009

I'm not sure how best to diagnose this, but I am seeing some odd issues with the query workbench and cbq.

I created an index (defer=true if it matters) and then when I tried to drop that same index a few seconds later, it said that it could not be found:
[

{ "code": 5000, "msg": "GSI index table2 not found.", "query_from_user": "drop index default.table2;" }

]

The indexes are present in the UI as well as system:indexes.

There don't seem to be any errors in the query.log on the node of the workbench:
