[Glitch] Won't let me play heroes or spells after troops played

So I placed all of my troops and then when I went to play the heroes and spells it would not let me no matter what I did. I could select them but it would not let me place them anywhere. I had to just watch the rest of the troops do their thing until they were all killed. Internet connection was/is fine. Anyone else seen this bug? via /r/ClashOfClans http://ift.tt/2xtYOKG
