I'm trying to do the "Egg" achievement, I've followed the guide on here but it's not unlocking for me, am I doing something wrong? D:

I am 12 hours into this game, I was working on my last 2 achievements (all items and all recipes) and my data is just gone. I'm so upset. I didn't have a manual save thinking I shouldn't need one, so I'm guessing all that effort is just gone? I really don't want to have to restart....

Guides say you have to turn on light mode. But for me it didn't trigger.

Just launched the game and have no elements to combine at all?

Well, it was fun until now. Closed the game half an hour ago, restarted it now, and it was all gone. Considering how much time it all take because the game runs terribly slow on my pretty much average laptop, maybe it is a hint. Just would like to know whether it is a common effect or rare....
