I fought tequatl. DId a whole lot of damage to him. he died. Chest icon shows up on mini map but didn't actually show up. I can bump into the statue (chest) but i can't interact with it because it's invisible.. Help!
Did you get the loot into your inventory, perhaps? If you have the Pact Commander core mastery track maxed, you have the option to loot reward chests automatically, in which case you won't be able to interact with the chest in the world as the game places the loot directly into your inventory.
If the statue is actually invisible in the world and you are still on the map, report it through the in-game bug report system with a screenshot. You might want to try the event again at a later time, too, if you can, to see if the issue persists.
I do have pact commander core mastery track maxed, but i have all looting options un clicked in the options menu. The issue resolved itself when i fought tequatl again.
Glad to hear it was probably only a one time thing. Have a great day!
