Inferno Den portal will not spawn for a player for at least a day if disconnected after entering.
More details:
I believe this bug occurs because rewards for fighting the wolf are based on the amount of damage inflicted on it. Because the player is unable to fight the wolf at all, the game essentially tries to reward the player nothing after it's defeated, meaning a light bulb bubble never appears for the player to reset the spawn on their end. This forces them to wait for the reward period to expire (almost a day from what I've gathered) before the portal spawns again. I've lost 3 boxes because of this.
Steps to reproduce:
1. Enter portal.
2. Allow game to disconnect or crash before character spawns in Inferno Den.
Pretty much this. I wish they'd remove it already. No other MMO has this sort of thing. It's horrible. Players have made this suggestion time and time again for years it's a wonder why it still hasn't been changed.
Easy guess: It hasn't been changed because Nexon fears that the demand for Cash Shop cubes would drop if everyone could afford to keep a meister smith on their account.
Pretty much, yeah. It's about the money. There are somethings they could do though:
1. Keep decay but make players unable to decay below a tier already achieved (a meister can't become an MC and an MC can't become Lv. 10).
2. Get rid of decay but double or even triple the mastery needed to achieve the next tier.
3. Get rid of decay and increase the items needed to craft things.
4. Get rid of decay, red cubes, and lower the price on black cubes.
5. Get rid of decay and increase the price on using MCC/MC on items substantially. Require a price regardless of the item's level.
