The objective to defeat the wave is blocked if the Mix.R is completed before the fight.

• Enemies never arrive.
• The objective does not complete: Defeat the stranger’s forces.

Steps to Reproduce:

1. Start a new game.
2. Progress until the tutorial is completed.
3. Go directly to all four antennas and stashes to unlock the MIX.R quest.
4. Complete the MIX.R event.
5. Continue progressing through the main quest until spike traps can be crafted.
6. When the O.R.C. wave triggers, observe that no enemies spawn and the objective to defeat them cannot be completed.
