Actually, the current delay seems more legitimate than the last four. That's not to say that it is legitimate, since we don't know whether or not Alishia was involved in any of the protests currently going on in Russia. It may or may not be legit. But massive political unrest in your homeland is a better excuse for a delay than just admitting that you failed to put in any work, which is what her October delay amounted to. Regardless of whether Alishia or Lizzy personally got swept up in the turmoil, it stands to reason that they would be affected.
The real problem is that the update should have been released months ago, before things got hot and heavy in Russia. Now we just have to wait and see how things shake out. Hopefully, Alishia and Lizzy won't be directly impacted, and the update will be released soon. But I won't hold my breath.
