@tfardet I don’t know about the vertical and horizontal “diffraction spike” lines; I’m curious about those too. Scraping generally looks like rectangles and is far more visible in @pnorman’s hourly visualization. The Null Island radiants are, I’ve been told, relocations that improperly do a smooth pan instead of teleporting directly from Null Island to somewhere actually intended. So you’re right that they shouldn’t request intermediate tiles, but they do.
