Hey,
sorry the last days were quite busy and I was not aware about that ticket. I guess I read it and did not mark it to check it 
So one thing, as said to all the others: If a structure is deleted, stay in that playfield for 10 minutes and the structure list will be updated. This is needed. Not much we can do.
If a structure just vanished, let us know, we restore it.
7864430 indeed was just gone. Game bug. But it has nothing to do with recycle. If you want this restored, let me know agin.
If recycle does not work, please make sure to let us know the error the game gives you about it in the chat.

So all your recylce tries afterwards did not work of course.
After I waited a few minutes in the Orbit, your structures now show deleted on its own. SO this ticket could have been fixed by a player (besides restoring the one structure that was deleted by a bug)
