In mangosd.conf there's "RabbitDay" (default 0/off). What does it do? https://github.com/mangosone/server/blob/8acb9fb60f4a514eb0f8fb8244a8f3f40cb30a8e/src/game/Object/Creature.cpp#L1737 Edit: I have a hint; noticed "CastSpell(this, 10710 + urand(0, 2), true);", went ingame and did .cast 10710, and got a rabbit (+1 and +2 also do rabbits). I guess it should be set in Unix-time to whenever Easter is if I want a random rabbit as a companion on log-in for that day? Or is there an actual Rabbit day in WoW? Or the international one at the end of September maybe?
