A game, specifically nms, has received lots of updates changing the game mechanics. the time that was achieved for center% was made in 1.0, and is not possible in the current game. say we wanted to accept wr runs from the latest patch, but they would be obsolite due to the old run. what would you do in that situation?

Create a new category specifically for the 1.0 version and then have the main category be any runs that aren't on that version. That way you still keep a record of all the old 1.0 versions but now people can submit runs with newer patches and not have to worry about a 1.0 run exploiting a now fixed glitch or mechanic or something like that.
