I've completed the first cycle of sunken chests and was able to go through a second cycle fine except for the Sunken Chest in Lornar's pass. I've seen other players interact with it so surrounding events aren't affecting it and I have a key so there shouldn't be a reason as to why I can't access it. The chest appears open to me with no tag name above it and no interaction prompt. It's keeping me from progressing forward with gathering the Swim Speed Infusions. https://i.imgur.com/F7H1uqF.jpg I've linked two images to show what's going on.
Got the same problem, did everything. Renamed folder, deleted folder, etc. Even with new one made automaticall by taking a screenshot it still says its full.
