I see no explanation for the 2 x "oops" in XKCD 3266
XKCD 3266 posted today (07/02/2026 - for posterity 😆 ) Has two annotations "oops" - it seems to imply that some of the deep excavations ran into some issue or non-lethat accident? But at the same time the overlaying entities are geographically dispersed, so maybe it's just a Randall "oops" in drawing?
