Unknown Chest
I’ve been seeing that as well, and also on some interactable trees. Assuming it’s just a glitch.
L.F.E.
They forgot to disable the nameplate and left the name of the object blank, thus it defaults to Unknown.
I wonder if this coincides with the issue i am having with not seeing chests open or make a sound when i pop them, but when other people open them i see the graphic and hear the sound. Perplexing indeed.
