I believe everyone experiences this issue.
When you open Dungeon VII Mount Gobknocker, if you tap on “Warlords Rising Set” to see the loot table, the game will crash (loading circle keep rotating on the bottom right corner) and you cannot do anything in game - so you have to force close the game.
I want to add that related to this issue, every time you get Dungeon Chest from completing Dungeon VII - Mount Gobknocker, there is a possibility that when you open your chest (either by using key or by minions) you’ll get Server Error message - forcing you to restart the game.
Every Dungeon Chest from Dungeon VII usually causes this Server Error Message to appear TWICE.
So we are forced to restart our game TWICE too.
Only after that we can open the chest but usually the content is lackluster - I assume it’s because the game removed the troublesome shard/rune from the chest therefore the chest’s content is usually bad.
I believe this Dungeon VII chest issue may be caused by the same bug (missing asset for the rune/shard).
