Hey all, sorry for the trouble!
It looks like a change was made to the way tasks are stored in iCloud. We've since been able to track down exactly what we need to change to skip over data loss, but, of course, will need to wait for Apple's approval once we're ready to submit.
In the meantime, it really would be best to completely disable Siri at the OmniFocus level; OmniFocus Settings→iCloud Reminders→Off.
We're really sorry for any tasks that might've been lost in the past day*— stay tuned for more updates.
