On May 1st, We received multiple feedbacks from our players about the game freezes or stop running.
We looked into the issue and found out that some files on the Steam Cloud might be broken. We've upload the fixed files and this should be able to fix the said problem.
If you've encountered this problem, please update to V2.0.9 and try again. If the problem still exists, please temporarily disable your anti-virus software or firewall and retry, and contact us in this post.
