Snapshot height does not match

What does this mean? I already resynched my SPV file, which was a nightmare of its own.

“Warning
An error occurred at task: ProcessOfferAvailabilityResponse
Cannot take offer because snapshot height does not match. Probably your DAO data are not synced.”

Spv is for Bitcoin wallet state only, while DAO resync is only for DAO state.
This messages indicates that you and your peer have different DAO data. Go to DAO - network monitor and look if changes are needed. Maybe it’s your peer who is not in sync.
