I want to report a rather major bug.
Not sure if you're aware of it, but I wouldn't be surprised, just saying in case you weren't.
The scene shortly before the route split happens, when the bad guys crash the ceremony, the game softlocks when the enemies attack the NPCs.
I looked into it and looks like they're attacking units who aren't fielded ... I think.
It's been a week already, but you'll see when you check.
Also, was making longbows locked to archers and snipers intentional?
Because they're still a lot of generics running around with longbows, like warriors and silver knights.
