Description: When I launch on a terror site mission it sticks at 99% for upwards of 5-10 minutes. I have replicated it twice now after I have to use Ctrl-Alt-Del to pull up the task manager and stop the game and then restart from the beginning menu. I have not tried to skip a terror site mission yet. This is happening within the first 2 months of in game time.
What Happened: I clicked on the terror site mission and assigned my troops and launched on the mission and the game hung up for anywhere from 5-10 minutes.
Further information: Using the autosave I loaded the last save and then proceeded to send small teams on mini-missions as I call them to gain money or scientists and engineers. When they return there is a terror site mission that will pop up and I click on it and it hangs up the game.
