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.
and 4 others.
