Lets say I took the vault 13 map and edited it. Is there a way to get the vault 13 map I made into the game so that it replaces the original vault 13 map?
if it's a game you already started, and have already been to vault 13, then the new map will not be used..
the game saves a "local" copy of the map in the save game folder so it doesn't loose things you put in lockers and drop on the floor etc..
