Upgraded hero while in dialog

[PaulWesley]

So I played the lvl where you unlock the third hero. She appears and it starts a dialog. I was too lazy to read it so I spammed spacebar to skip these texts (may add a skip button to skip it all?). Before the dialog started I had selected a champion ... because I spammed space bar I accidentally upgradet him

So you should block upgrading heros while in dialog (and add a skip button to skip it all)^^
