Sorry to trickle in a typo, but on the highly anticipated objective, Marked for Destruction, there is a place in Special Rule where "Then assign an objective token to the attacker " should read "assign an objective token to the defender ".
I don't know if anything can be done about this one, but just to do some field journalism here... our group was using the app to manage a campaign (and loving it), but had to drop a couple of guys after Christmas break who were then replaced with 2 new guys. Unfortunately, the 2 new guys couldn't manage the fleets that they assumed command of, and they couldn't be added to the campaign roster to make a new one.
There are a myriad of ways to deal with this, but all of them took some creative jury rigging or sharing of login credentials. We easily are making it work, but I wonder if there is a functional reason we need to lock the roster once setup is completed, or if adding a new player after the fact could be made possible. That seems like something that could be explored while you are messing with scaling the number of participating fleets.
This is not any kind of deal breaker for me, I love having the guys being able to access the campaign info themselves when not at my house.
I hope you are enjoying the build, we are!
