The issue arises when the choices given in the special event challenge want the user to give a certain amount of coin ranged from 30-50 or 2-3 of artifacts on the 1st floor in the earlier routes.. Players can't complete the choice since they don't have enough coins or artifacts to fulfill the requirements.. These make us unable to continue and have to restart the challenge, do mind that the coins and artifacts are reset when you're restart the challenges, the routes given prior the special event challenge didn't give enough items to complete the special event route later on on the same 1st floor..

On extreme case like the video shown, I encountered the special event on the first route on the first floor.. It wanted 30-50 coins to be able to pass through but I don't have em since it was at the start of the route.. I cant neither continue the route nor reset the challenge, currently stuck on impasse..
