It’s still acting up, probably because of something else. I made a simple VA GH Style Element with Blocks. After closing and reopening Rhino file for some reason they Elements disappear during any modifications to the Style configuration or moving any instance of a given Style configuration.

BTW.
Running Purge command in Rhino will delete Blocks referenced by VA GH Styles which is of course a disaster.
Also, while copying Element that references some Block Definition to the file without that Block, Block Definition is not copied along, so element disappears.
