Steps:
1. Apply Heavy Thrust from a non-flank position. Since 2.45, this now applies the Heavy Thrust buff.
2. Despite having Heavy Thrust buff, the Ring of Thorns skill icon does not have the flashing ring around it to indicate it is activated as part of a combo.
3. Using Rings of Thorns despite having the Heavy Thrust buff does not increase Ring of Thorns damage beyond the base damage increase for all skills from the Heavy Thrust buff (the combo is supposed to raise the base damage of Ring of Thorns to 150 from 100)
4. Applying Heavy Thrust from a flank position as it was originally intended prior to 2.45 still correctly applies the Heavy Thrust buff.
5. Applying Heavy Thrust from a flank position does indicate that Ring of Thorns is activated as part of a combo by putting the flashing ring around the skill icon.
6. Using Ring of Thorns after applying Heavy Thrust from a flank position gives a significant increase to the damage from Ring of Thorns.
