In some rare cases OMEMO identity and private key are lost from the database leading to issues with encryption and decryption of OMEMO encrypted messages on a particular device.

This issue occurs more often if OMEMO-MUC is used as it more often manipulates OMEMO identities (fingerprint, public keys, etc).

It looks like the incoming message in some rare cases overwritten users private key in the storage leading to issues with encryption/decryption of the messages. This issue should be solved now.
