I tried out the Exult nightly from 6 January 2015 and started a new game. Teleported almost immediately to the throne of LB. Asked him to heal me.
He then said "Indeed this person is badly wounded. I will attempt to return them to health.", followed by "Thou seemest quite healthy!"
Same thing when I asked him to heal Iolo.
This is how the usecode for LB is written. Nothing to be done about it. Same thing in the original.
