After spending half saturday re-creating the mission file which causes this problem, I finally found the problem. It turns out that I am using a divider in the trigger list to make it easier to group the various triggers. I use a notation lige ++++++++++++ BDA Score +++++++++++++++. The conditions are empty, and I put the "Begin acting player (1)" statement in the ACTIONS. This is something I picked up in a youtube video. It turns out that this is the line which is causing the problem. I deleted the trigger, and then everything worked just fine.
