Anybody know? I'm looking at starting up research again, and the answer to this question has impressively dire implications. When I unrented an office recently it said that any jobs installed from that office would fail and be delivered to impound, rather than completing first. An ownership change presumably unrents offices, same as it revokes clone contracts, and according to evelopedia items in impound are undeliverable if the new owners don't allow you to rent offices there.
Research costs real money now, so if jobs from personal hangars also fail, that's pretty bad for me. If the blueprints are then delivered to impound, that's very, very bad for me. So if anybody has an answer to this, please share.
Alternatively, if anybody knows somebody who owns a station and who would be willing to experiment, we should be able to test this just by playing with standings.
