We have just pushed live a required update for clients and servers. This update fixes a case where dosh vault crates were not being properly granted.
While players will not see any missing vault crates returned to them with this update we are committed to rewarding players in the future. We are currently looking at options and the tech hurdles it will take to accomplish this and will message more once we have a firm answer of how this will work.
Once again thank you for your patience, and please let us know if other issues arise.
