Affects Version/s: Minecraft 18w20c
Fix Version/s: None
Environment:OS: Ubuntu with the Minecraft Snap package (but it also happens on my PC and my Mac)
Java version: 8 (_Not_ OpenJDK, proprietory Java)
Core i3, Intel integrated graphics
I like to sync my Minecraft saves across my computers, so when I first go Minecraft I symlinked the saves directory to a folder in Dropbox. This worked fine, except when I started testing the Update Aquatic snapshots (I started with 18w07a), it crashed throwing a [code] java.lang.RuntimeException: java.nio.file.FileAlreadyExistsException[/code]. I originally thought that it was clashing with my 1.12 worlds and put it in a separate directory. However, further testing revealed that it was crashing due to my symlink system.
I commenced a series of further tests, the most recent of which involved emptying Dropbox to ensure that none of my files were causing the crash. The output of said test I enclose in a TXT file attached to this report.
Please fix this as soon as possible, as I like my worlds to sync
