For information on the Multi-Ind asset problem see this thread:

Basically, I reported a problem with the various industry assets to the Helpdesk and they have confirmed my observations as a bug. The bug will be fixed in the next game update.
Sorry that I haven't followed this thread recently so you all have been chasing something that the N3V boys have to fix.
Take care,
