Bug on the last mission - Legendary conflict

[Diogo]

So, I was doing the last mission's bonus objectives, and since I had to use a non-army deck, I tried to use the last Boss card. However, it seems to have a certain characteristic that makes it so there can only be one of those in play.

I had a very solid squad and nothing would survive, so I just waited for the Boss to spawn... which it did not.

I'm not sure if this is actually a bug or if it was intentional, but I thought it would be useful to post.

On the last level, do not use that card, it will only cause problem, haha!

This may be related: I usually beat that level in ~30 rounds (record 24, average around 32), but sometimes when i have a really awesome squad I noticed the boss "chickens out" and refuses to show up for like 20+ rounds, ocasionally sending just a few troops to try to weaken me. When that happens map only ends after 50+ rounds. Once it ended after round 66! This was before I beat it for the first time, so it might not be related at all with the boss cards set.

TL;DR: This behavior might be by design. Eventually the boss will show up, but that might take as much as 20, 30 turns, and it might not be related to the cards at all

By the way, can you clarify to me this "non-army deck" requirement? It means no card from the USA/Union faction?

I can't remember exactly, but I think that was it, USA's faction.

Hmm, yes, perhaps it was just taking too long. I beat it, but I did change my deck (and took the Boss card out).
I thought it was an interesting thing to happen, since the Boss card was unique, so there should be only one at play at any given time.
