How to edit map without having to change the name?

[polartop]

hello, i made a map recently and i found some glitches, it's trade_island_unusual_prtf2 i want to edit the map and fix these problems but i want to keep the name and not have people get the "map differs" error, suggestions?

Can't be done.

Yes, it can, i went to a map that had rain in it, it made some people lag so they got rid of it, and they didn't have to change the map name.
