For those not following Discord or Telegram:

Upgrading wallet to version 2.3 is required!
This is a mandatory update with fork at block 560000. All the info on the GitHub page https://github.com/avymantech/lobstex/releases

For those who still have some zlobs: convert the zlobs into Lobs asap. Zerocoin protocol has been removed from the wallet due to its recently discovered vulnerabilities.
