My Lands: Black Gem Hunting

My hero is stunned for days and I cant get him 'unstunned'?
After loosing a battle the hero got stunned and there was a tooltip saying it will be stunned until April the 5th...but now its a day overdue and it is still stunned.
I tried taking him out of the sanctuary and sending into a robbery mission but it wouldn't let me.

Is there something I need to do with the hero to get him un-stunned?

Hello Ivan

i see you ingame, you are 1star level - Esquire

To have a hero working you need to be level 2 - Captain

You see when you dum hit the ruin you fell level, so no worries onece again you get to 2* lvl you will have your hero.

g thnx, would never thought something so simple
And all this days I was trying hard to stay 1 star as there are next to no cities I can rob once I reach level 2
