TBD, Anchor report has not been released yet, even though contest was in May 2022
Seems like it was an issue of validators mixing up the price of LUNA 1.0 and LUNA 2.0 during the migration to Luna 2.0. Seems very doubftul that code audited by C4 in March would have been the cause of this unplanned migration to LUNA 2.0
