Patch to version 22.214.171.124 is out now. The game will be automatically updated when Steam client is restarted.
In this version the broken challenge chapter 14.1 has been fixed, moderate difficulty's balance adjusted and the scoring changed so that playing on harder difficulties grants more score. We also added one new achievement and a separate leaderboard for Arcade mode. Rare issues with missing research tokens and the level selector were also fixed among other minor stability issues.
