Why does it say that i don't have the raw material when i have 2 gears https://tinypic.host/image/DViNfw

twice now I've had an issue where after selling an item off the store shelves and receiving money, the text box refuses to progress, leaving me locked out of progression... usually i'd just restart a save and move on but the prologue doesn't have saving!

Here is some gameplay of the game with some feedback for the devs. The repair shop bugged out for me (couldnt repair nothing),have better tutorial explaining how the repair shop works,the spectometer (to see the materials the object is made) needs a better tutorial on how to use it,sometimes when i buy a item even when i use the pc the game sends a email saying that i didnt use tool:computer, better tutorial on how to use the magnifying glass ( needs to say that you need to find something). https://www.yo...

Is there any way to save the game? I ran into a bug twice and couldn't continue playing but that also lead to me needing to start from the beginning. It's a bit of a pain when you are a few days in..

Add some, please! ^_^
