During our last play we've faced an issue regarding skill tokens in battle regions. Here how it went:
1. Machines entered a region with Trog token - 1 Trog came up. Battle Region token was placed in the region.
2. Machines placed Firepower token in the region.
3. Humans placed Seek and Destroy token in the same region.
4. Machines killed Trog with Drones. Battle Region token was removed.
#1: What should've happened to Firepower and Seek and Destroy tokens? We've removed them, since no Battle Region = no related tokens?
#2: If tokens should've stayed, could Humans use Seek and Destroy token if they've entered the region and became the Attacker?
#3: If tokens should've stayed and no battle took place, at what point those tokens should've been removed from the region?
#4: This one is battle resolution related, if for some reason there are no units in first Battle Objective, should the Defender get 2 VPs?
