Weird issues with texture streaming

(All in editor) So I suddenly started getting Texture streaming pool over X mb warning. This is odd for several reasons. First, it seemed to have appeared out of nowhere and jump straight to 100s of mbs. Second, it shows the warning even when I fly up and look into up into the sky that has been there from the start and never gave that the warning, or even when I look down at the floor, which, too, has never returned a streaming pool warning. On top of all that, sometimes it doesn’t appear at all, or at relatively low numbers.
