Thanks Yah I think I know what it may be. Action group 8 (footbridge defense) was only enabled if the footbridge was blown when the tank arrived. And I assumed the tank would get to the next spline "past the bridge" within 10 seconds if the bridge was not blown. If it doesn't get to that next spline and the tank is damaged then the team that has the flag may not have goals for all classes.
So the simplest fix is to unconditionally activateAction_group 8 in action 46 test block (i.e. leaving the tunnel test). It should have only a slight effect (like; Allies less aggressive moving the tank between s102 and s103 splines) and the group will still be deactivated at the next spline (in action 52 test block). I'll update the aiscript and run some unattended tests next week before posting 0.44.
