We are currently tracking the skill reset bug across the board for market place units. It will hopefully be fixed by 1.24b which should be coming out here within the next week or so. Thank you for your patience and reporting this bug to us. If there is anything else you need please let me know.
If I always appear prepared, it is because before entering on an undertaking, I have meditated for long and foreseen what may occur.
