Omada LXC stops functioning after update, can't start mongodb

[Cheshire92]

Hello, I've updated my LXC container with the update command and this gives me the following output:

  ____                      __     
  / __ \____ ___  ____ _____/ /___ _

It no longer appears to start the MongoDB server, is this a known thing or do I have to go fidget with it?
