Game crash when using symbolic link for "saves" directory with ownCloud

On version 18w14b, the game crashes when linking the "saves" directory with a ownCloud storage by using symbolic links. Doesn't crash on 1.12.2. Didn't test with DropBox because it's garbage since I uninstalled it. 😛

Command I used is :

mklink /D saves "*somedirectory*\saves"
