Hey guys!
Subnautica is currently in Early Access and as such you may from time to time encounter bugs and in the worst case, crashes. If you have issues with stability of Subnautica, please post your issues with as much detail as possible (video/screenshots/descriptions), followed by the following requested information:
Example Topic Title:
[Crash] Open my Locker and Crash! [Version Number]
1) Please run dxdiag.exe (search windows for it) on your systems and hit the button 'save all information' in the bottom right. Save this file for later.

2) Navigate to your Subnautica Folder in Steam (should be steamapps\common\Subnautica)
3) Open the Subnautica_Data folder and grab a copy of 'output_log.txt'

4) Upload all the text of these to something like http://pastebin.com/ and post the public links to them with your forum posts.
These 2 files will GREATLY help us in tracking down issues with Subnautica. Thanks!
