engine logs and screenshot

Description of problem:
After attempting to move a host from one datacenter to another (and failing with NullPointerException) the host appears twice in the hosts view. Selecting one host selects both of them. 

vds_static only has 3 entries (there are 3 distinct hosts in this setup):
engine=# SELECT vds_id from vds_static ;
                vds_id                
--------------------------------------
 eecec242-6e65-4fde-b3d5-16d750434c7a
 f87fa930-8a1f-4579-884e-df36a898cb5b
 d6fade3c-7bf7-4e7a-972e-205b41e993fb
(3 rows)



so does vds_dynamic:
engine=# SELECT vds_id from vds_dynamic;
                vds_id                
--------------------------------------
 eecec242-6e65-4fde-b3d5-16d750434c7a
 f87fa930-8a1f-4579-884e-df36a898cb5b
 d6fade3c-7bf7-4e7a-972e-205b41e993fb
(3 rows)

however vds_with_tags shows duplicate entry:
engine=# select vds_group_id, vds_id, host_name from vds_with_tags;
             vds_group_id             |                vds_id                |            host_name
