Hi to all, I am new to 0AD and its community. I have created a new map in svn sources path, all was fine but today. I updated the svn sources (without launching compilation), an runtime error occurred in some js file. I continued in atlas editor and loaded my map, many errors come out about don't remember what, but all objects I was added disappeared, only few objects of the old map are at their place. After this I built the sources, an error occurred. I ignored the errors, edited and saved the map with old binaries and loosed all the new objects I added, this is not a problem, the objects was there to test proportions (almost trees and bushes), but I cannot test the map with units (pathfinders). Now, I can continue to edit the map for terraforming (still 5/8 to do), surely in about few days this problem will be fixed. I'm thinking to make a copy of a stable svn compilation, I currently working on this map from about one month (a couple of hours a day and not every day, more or less). My question is: It could be happen that after an successful update/build/copy some objects will disappear from the map, due to refactoring/renaming or something else? If yes, is there a way to prevent this, or at least a lane to follow? This game is in deep development state, I am prepared for the eventuality of loosing something.
