Well...

There have been no changes that would affect your subscriptions and other people's subscriptions seem unaffected.

So I'd have to guess you either did something (I don't know what), or there is some bug that affects subscriptions.

Either way, any details of what you might have done recently regarding subscriptions would be helpful.

It would seem unlikely that a bug could affect (and delete) the subscription records. The subscriptions are stored as individual records in a database table. The "bug" would have to repetitively affect multiple records.
