Here they are talking about sublots, not lots themselves.
Anyway, you can easly mess up lot creation. So it would need to be really fail-proof for it to work with players.
Cause if you mess up, it isn't a one-click restore. (if it even can be restored)
Anyway, I agree with Skye. If we ever change the system again (and we done this like 30 times) we would need to inform everyone, as well as education them.
