BOTH cruisers will spawn once the RTB is reached, instead of the previous single only - which lead to mission completion impossible

- The mission was previously way too easy. Turns out I forgot to activate the enemy brains. as a result, the enemy is way harder and comes from different directions.

- Adjusted spawns and designated target groups for better and more difficult gameplay.

- Added better paths and trigger areas to get a more seamless transition between objectives.
