If you leave a session without fully levelling up, all progress to the next level is gone. Puzzles need to be redone when re-entering a level (Not sure if this was a feature) As you know I am a big fan of these games, but this is a little worrying Updated- Removed bugs that are not bugs...

After 1000 hrs I finally have all the rocks at lvl 100 and gotten all achievements except for the basic rock one (which was the first rock I got to lvl 100) pls help I want the completion really bad and dont know how to fix this bug.

I found 3 on the first map, and 7 or 8 on roof but that's not enough for both maps.

Aurora's puzzle won't work. When I turn all three rocks green, the rocks don't blink and go to the next stage. This results in at least 3 unlockable achievements. https://steamuserimages-a.akamaihd.net/ugc/2455115325855189234/ECA32BEEE45B97F6FF106B74C5793B637D7438C9/?imw=5000&imh=5000&ima=fit&impolicy=Letterbox&imcolor=%23000000&letterbox=false...

is anyone else getting "Error : 1074" when in game or know what causes it, or is it just me?
