This is impossible to reach the 100 points reward in the event lugbug quest, event lasts for 3 weeks, you can get 16 points per week from the weeklies and 2 points per day from the daily, which amounts to 16x3+2x21=90 points
Considering we had a bugged reset after 2 days when the event started, we could get 6 more points from the weeklies (no time to do the 2x 5 point weeklies in 2 days) which amount to a grand total of 96 points.
The reward wasn't even much, barely 2 bags of farm medals, so it brings yet again a very recurrent question : Was this event even tested ?
