Demolish still triggers and just fizzles when there is an indestructible support on the field.
Concur. Saw this today.
I can verify this as well.
Node Rule supports also count as supports for TSN and Storm the Vault. Probably a related issue.
I saw this yesterday too.
On a related issue today I cast a Meteor Golem, when the only things my opponent had in play were the indestructible node support (Nicol Bolas Rising(m and an Avaricious Dragon, and neither was destroyed.
