I had a similar problem. I was playing mahjong and went out of possibilities so I got the message and clicked on it to start again. The game dismissed and all I could do was start a new one (more or less, but like I had no game currently playing). As I didn't want to use energy to start a game, I reloaded the page and, on the mahjong page, I got my game just before I clicked on the last pair. If I clicked it again, the problem repeats.
I left the page and reopened it and open it again in an other tab and it worked. Really didn't know what was the trouble but if it fixes your problem, it's worth a try
