If in the AI-squad (for example, it is a tank platoon) there are repair-specialists or engineers and there is a damaged tank (or other vehicle), then after damage the AI-commander of this squad will order to repair the damaged vehicle. This is good, but if the damaged tank is destroyed before the repairman will accept this order and will responds - "I understand", then this voice-command gets an endless loop on this order.

It is impossible to stop and player just need to restart the mission.
