This has happened to me as well on the last 2 updates
iPhone 6 10.0.2
iPad 4 10.0.2
With both devices, bug occurred on v1.1.4.0 and v1.1.4.1
The party is now unplayable when either option (heal or continue) are selected.
Buttons appear clickable, but nothing happens when you select any of them.
Had to start a new party to play.
Is there a bug tracker you use for this kind of stuff like bugzilla or jira?
