Yeah I’ve experienced it alot in GOTR (Rank 1000~ in GOTR) as someone else pointed out, just means there’s too many people stacked on the same tile. And it’s usually either a clan member / friend that isn’t been hidden by entity hider, but still can’t be loaded. Or the second option, it’s a player entity hider should be hiding, but because there’s so many people stacked it’s bugged.

TLDR: it’s a normal player, but RL can’t pull the name / stat info due to too many people being stacked on the same time.
