Journeyman Toymaker bug
Try doing the wintersday related achievement in the Daily Achievements (I think today was hitting 5 people with a snowball). Those should count towards the meta.
Daily achievs count to the meta.
do 3 more dailys and you should get it
same problem, the repeatables don’t seem to count towards it even though it says they are supposed to in the checklist.
As drowze and lLobo stated, you’ll have to tackle some Wintersday dailies. I believe the repeatables only count once toward the meta, but WD dailies should fill any other gaps you need.
The Dailies are super easy (but do require playing potentially more days total) and let you avoid any of the others you aren’t interested in.
