Same thing happened to me today. I spent 233 crystals to finish an expansion. BIG FREAK OUT! I however got my crystals back.

As soon as I realised I spent the crystals I switched on airplane mode on my Iphone. Then instantly returned to the game to collect some more coins and wait for the 'lost connection to server'. That however didn't show. But I figured the game didn't have time to process everything yet. So then switched my phone on and off and then luckily my crystals were returned and my expansion is now still being built.
