Some weeks ago, I started a new project on RPG Maker VX Ace, I was messing around with it for one hour straight, testing the engine and etc. Everything was going fine, I had just saved the project and was preparing to close it, but before I could click on the "X" to close the project... the lights went out, nad when they returned, I checked the project to see if everything was OK, and all the files on the "Data" folder were corrupted. How I realized that? The project displayed a message that can basically be summed in "the project cannot be opened", I tried to open it like if there's no tommorow then I deleted the "Game.rvproj" file and replaced it with another from other project, and a message saying that the "Actors" database could not be loaded, so I replaced it, and the project said the same thing about the "Itens" tab. In this moment I realized that the only way to fix the problem was to replace the files in the "Data" folder one-by-one, and since I had no backup of the project I had just started... Thankfully, the only things I modified were the Actors and Tilesets, but imagine how dangerous would it be if the project was on a more advanced stage. So, what should I do to prevent this from happening again?
