Lost the Piano Roll but Music Still There

Having trouble with LMMS? Ask about it here.
Sorry for the trouble, and many thanks!

They appears as mousegray rectangles.
An empty block is then meant to be either:
* right-clicked, and opened in piano-roll
* used as a reception-block for a block that has been either copied or cut

You can simply middle-mouse click each of them, and they will disappear, and under the empties, you will find your missing notes :P

I should have figured this out, without having your file ::facepalm
So no. your project is not corrupt, nor is this a bug
Oh man! Of course. It all makes now. :P
Epic facepalm to me too. :P
How the heck didn't I realise, that that was what was causing, the disappearing notes? Lol! :P
