I find many Korach commentaries annoying

Let me put this bluntly--there was no such thing as cloning in biblical times, so Korach could not have been swallowed up by the earth around his tent because he was at the entrance to the Tent of Meeting at the time.  A lot of commentary annoys me because it supports the tradition that Korach was swallowed up by the earth when the text does not necessarily support that interpretation.  As far as I'm concerned, Korach was killed at the Tent of Meeting along with all the other rebellious Levites.  That's my opinion and I'm sticking to it.
