Wrong placement of block

[worldpotato]

I moved a block just before it lands on top of another and then it got "stuck" midair with just the edges touching.
I also uploaded an image with the result: https://imgur.com/AyG4VPA where the blue left L shaped block stays in the air.

I think that block should drop to the lowest possible solution.

I'd guess it has something to do with the rotation mechanism; it looks to me like you were rotating the block at that time? I don't really have the time right now to track this down; this code was honestly meant as a "learn C++ project" for me, so I didn't expect many people to be interested. When possible, I'm going to do an almost full rewrite, so I'll investigate this more then. In the meantime, if someone wants to submit a PR, I'd be happy to merge it.

To be hones, I don't remember. But it's possible.
It's a cool "learning project" I have another "learning project" at the moment. But maybe I'll come back and do sume further investigation there.
