I’ve just tried to access the “Weaving Supplies” treasure but have encountered a bug preventing me from doing so. In order to loot this treasure you’ve got to collect 3 different coloured threads from a location nearby, this will then give you access.
The issue I am currently facing is the “Violet Thread” isn’t lootable, it shows me an empty bag upon clicking on it providing me no loot, Leaving me permanently 1 thread short and unable to open the chest. I have re-logged, disabled addons and I’ve waited a while to try again, to no avail.
