If a Plot Group is deleted, but is imported again using the sample/occurrence importer, then the Plot Group will not be imported.
I believe this is caused on the Warehouse side which uses the database function insert_term to create new Plot Groups in the Plot Groups termlist, I believe this function has a bug in it which means when it checks if a term already exists, it isn't checking the deleted flag
