Those who had between 5 and 30 placed kegs before the patch and got auto-rewarded the achievement did not have it count towards “Triple Trouble”
Eg: If you were on 9 / 10 with only “Wurm Demolitionist” left, the patch gave you the achievement, but you remained on 9 / 10.
Whilst the Title is still possible due to the newly added achievement, you can have 10 / 11 completed, and not have the 10/10 title.
