Android play machine + analysis broken

Play against the machine gives: Error. Invalid FEN.

And analysis is still broken when you access it from a tactics problem. The engine either doesn't start, or it does a few moves and then stops analysing and won't let you make further moves.

v4.5.3 Android

Can anyone reproduce this or is it just me?

1.) machine error: I am not sure how to reproduce. Playing the computer works for me.

2.) Broken analysis board after tactic puzzles: confirmed.
