[Gameplay] Maple Guide mount quests don't function
MapleStory 2 Rep: 200
I made a new character on NA - West, and was doing the Maple guides, along with a friend, the mount quests do not work. In the quest "High Octane", after you equip your car, it doesn't register you equiped it, nor can you move. The only way to move around is with your dash skill. Me and my friend have both waited an extended amount of time, to see if maybe it was just part of the guide where you have to wait for the NPCs to finish discussing or whatever. The same thing happens with the "Getting high for Science". After you equip the mount, it doesn't register you equipped it and then you can't move. We have both restarted numerous times, we have emoted to see if that will fix anything and it doesn't.
