Saving map without new UId

[steeffeen]

hey there

is there any chance to save a map again without causing to give it a new UId?
in my case I would like to modify the maps of a solo campaign without letting players lose their medals
(the actual way to finish the map won't change)

regards,
steff

Any change to the map (terraforming, objects, skining of signs) leads to a new UID, right?
Possibly only lightmap calculation and non functional changes like the description might be not affecting the UID.

What do you want to modify exactly?

i think you don't even have to change anything, just saving the map in the map editor leads to a new id, gonna have check that

i only want to change metadata, no actual blocks or mt stuff
just data like tags for blocks etc

well maybe a tool like mapedit is able to help me in my special case

Normally you can change a lot of elements like metadata, external dependencies (music, signs) and lightmaps without creating a new uid.

But I also had once the problem/bug that simply saving the map results in generating a new uid.
I solved that by using a backup file of the map (from MX). Looks like the game client changed the map without editing it.

One part of the uid is a hash of your login/nickname. Maybe changing your nickname will also lead to generate a new uid. I don't know.
