Friends, please tell me ...

no, most likely you will not see
try to zoom in on the page in a large size it is usually better notice the hidden puzzles
peredelat the mouse suspicious squares, everything that can move is outlined with a red frame

I still have more than half of this tournament monster left

yeah, I see a glitch if you save and reload the page, it doesn't disappear?

On the right edge of 2 things. Already increased, closed, opened, exited, turned off completely - does not help. Gone. And these places are not allow to put.

I have in the lower corner of this box already assembled the dark
maybe your have already collected, there can not be supplied, just for some reason white are:what
and if you deliberate else, the puzzle will close, I don't know
question to @Support

I see you have at least two circuits are not in the right place! One for the sky and one to the right of the nut, which is next to the tree

I'm afraid to upset You, but I was and collected again.

I see a lot of parts not in their places , the whole left corner in the sky and at the bottom , with the upper white square is a band that is a glitch, if during Assembly you have seen that detail flew it is unlikely that it will help.

I have not collected the dark parts, and the one in the sky is from the coil, but there is, some as if moved by 1 detail.
