World edit just dagg a hole in my moutain

These issues are fixed now (it should be safe to use WorldEdit again), however, there is unfortunately no way to undo the damage that has been caused Do you have a backup of your world?

There are no automatic backups, so they have to be created manually (by coping the world folder)

Falls es mit dem Backup nicht klappt, und du keine neue Welt erschaffen möchtest, kannst du versuchen,
die Schatten mit Erde aufzufüllen und dann wieder zu entfernen. Am besten mit dem Tool. Es ist
eine Menge Arbeit, aber zum Teil werden die Shadows verschwinden. Wenn es mit der Erde nicht überall
hinhaut, Lampen reinsetzen.
Ich hoffe irgendwann gibts eine Möglichkeit Berge, ohne Schatten zu erzeugen, abzutragen.

for auto saving games, I use git on my save files and commit after each sucessful play...

Version control lets you easily make checkpoints on the contents of your directory. It's mainly used for programming code but you can use it for anything.

You can download it for windows here : https://git-scm.com/

It should come with a command line tool. Simply navigate to where the Save folder is then...

git init

You now have a new git repository. Each time you play the game and you want to create a checkpoint, just exit the game and type the following:...

git add -A
git commit -m"Checkpoint from 9-22-2016"

Now you have a save and you can go back to that point

Some lets say disaster strikes! The Zombie hoards kill you, or your building disappeared, or you don't like the outcome of a build you did. Just rollback!

git whatchanged
*find the commit number of the change you want*
git checkout <commit number>

Now play the game on your last checkpoint
