"This tile is blocked"

[eiis1000]

I've introduced two new players to the tutorial and both found significant frustration when placing mining drills. On coal specifically, when a mining drill drops a coal and blocks the tile, it seems to be difficult for new players to understand that they must pick up the coal (F is not demonstrated either) and/or place a chest.

This is already shown by Compilatron, although a few people have posted that they did not trigger it. So I redid the section where it is shown and so it is more thorough.
