I just checked a few minutes ago and it looks like the plants I watered twice today and moved around are still watered and relocated and pets I put on a pet vendor later in the day are still on the vendor, so it doesn't look like they did much of a revert the second time they brought stuff down. I think the revert this morning might have been to fix some sort of a "bug"/exploit. I read something that said Origin got reverted all the way back to Friday morning, so that would seem to confirm that possibility.
I'm in the same boat with you, Raptor, on the accounts. Couldn't get all my accounts linked so I'm not sure how to update info on the ones that didn't link. Out of 16 accounts I tried to link, seven wouldn't confirm successfully. (And no, I don't have 16 active accounts.) Hoping that maybe they just haven't finished moving everything completely yet because otherwise there seems to be no rhyme or reason why some accounts linked successfully and others didn't.
