Same here. Using Bluestacks on PC (via Google Play) until I pick up a tablet soon. The disconnect/reconnect thing seems to be between turns- it looked like it would occur after every exploration to me.
The 'purchase bundle' button is greyed out for me, though I still can buy individual adventures and characters. They are, however, all listed at '-1 gold'.
Barring all of that, it seems really, really well done. Looking forward to digging into it.
