you need to have the enemy numbers down by the last wave my pc is 10 years old when i had issues i found i finished the map when i had the numbers down gut if you need me to i can give a 5 day grace time before the final wave.

The last wave occurs a crash issue

Thank you for the comment i did up the final wave to 50k over 2 days.

Great map but the waves are way to small for how much prep time you get.
