We've been facing a problem for a long time now where in extremely rare circumstances some players have their save file corrupted. This has been a very hard bug to fix as it is impossible to reproduce the issue, and with no correlation between affected players, we could not see how to approach the issue.
It seems like some anti-virus programs would prevent Hydroneer from saving, amongst other things.
Despite our efforts, that bug has defeated us time and time again.
until today!
We are deploying this new patch to fix this issue! Instead of corrupting the save file, the game will crash to desktop and give you an error telling you the save file was about to be corrupted. Now you'll be able to use the previous auto-save to load your game back up.

We hope you're enjoying Hydroneer :)
