Some events seem to have a slightly higher chance at getting the 2 LC "extra" boxes, though it might just be RNG. Previous event, I seemed to get them around 30% of the time.

Lucky we still have record of lc in forum wiki. The last record of 10 lc map reward are in Monopastrum event (http://harem-battle.club/wiki/Flower...ncient-Mansion). After that, we only receive 5 lc for clearing map.
