Right so I apparently misunderstood how some stuff works so:

Re-ordered mission chain because I need both missions to have chainproxy rewards.

It is now infil rescue (this should give you the soldier), then you wait a bit, THEN it's city center havoc (which now rewards the region unlock.)

Also region unlock should actually work properly now.

Added check for whether XCOM has researched Resistance Communications before Chain can spawn.

Blacklisted timer sitreps from being used for the City Center Havoc mission type.

Fixed reward description when chain progresses to rescuing personnel and made City Havoc mission more populated with enemies.

City Havoc Mission actually uses all eight squad members.

Adjusted chain so there's only one period of waiting during it.

Added check to make sure the chain doesn't spawn if you're at max contacts.

Fixed missing localization

Covert Action activity wasn't properly assigned
