Game hanged with Janus pal

Was just testing the new pal Janus… At the middle of my 5th attack, the game started moving slow and then just closed… Lost 14 trophies beacuse of this… Could not capture a screenshot. 

I’m using android phone and my troops was ogre, monk and wolf…

Anybody faced  the same issue? 

it is called Royal Revolt 2… not Janus
