[BUG] Mutating block and layer states

[meer]

I often encounter misbehavior of BlockOut. I did not found any possibility to debug. So, I tried practice mode to make screenshots (see below).

Before step x (first screenshot) the blue layer is already complete, however, it is not removed.

In step x the green layer is being completed.

In step x+1 (second screenshot)

• the blue layer was removed;
• the green layer is now blue; it should be removed too, however, one block is missing again (see red arrow).

Used version is 2.5-5.fc23 (on Fedora 23).
