I've been sick for a few days so I haven't had time to see what is going on on this section.
We have a big problem.
As I'm writing this, it's roughly 1 day and 10 hours until round 5 starts. Here's the problem: Team underworld Vault has to be ready before round 5 starts! So you guys have exactly 1 day and 10 hours to build the whole Vault.
I went to see your Vault just now. It said "zero cards". In little over one day it should say 240 cards.
What you guys need to do now is to start building your Vault asap!
