Maybe try this for the dynamite action:

action 0 // If the door has been DYNAMITED, then
{
// Connect the nodes through the door
node_connect 72 42 true

// Activate the Close-in Defense (Group 1), these are toggled on / off in action 2's tests
activateAction 17
activateAction 18
activateAction 28
}

I have a suspicion that the if_action_XXX test is only working for dynamite actions (possibly causing other problems if used for anything but) and that the if_obj_home test in action 2 is only working after the first doc grab.
