Hi!
Can’t complete the Magma Caverns map.
The Fires Below - Destroy the Soul Furnaces 2/3
There is nothing here, the game don’t show me what to do or where. Picture

The soul furnaces are there, however for some reason they are invisible.
You likely walk around the map and wait for a flame to be shot out at you from nothing, so you know where they are and can kill them indirectly.

This is still a problem. Can’t complete the map readily due to this bug. I know they’re they’re and invisible, but having to search the entire map is not fun at all.
