Hello Hunters,
After gathering information and logs from you we have now released a patch to address the level and item reset issue. We hope that this will now be stable for all players and you will no longer experience any issues with it.
Here are the patch notes from today:
*Removed all steam cloud saving functionality
*Added full local saving functionality to the game
* We fixed the achievement 'Bloodbath' to trigger correctly once 25 players were harvested.
You can discuss the patch in this Thread: http://steamcommunity.com/app/322920/discussions/3/133257636770883959/
Thank you all very much for your patience and help!
Cheers,
Stefan
