@ddsheils So i think I may have a fix, this worked for me. Swim across the river, walk up the track, go to the left, perform the leap of faith into the hay. Walk around the shore and Hytham should row over to meet you alone. Not the best fix, but seemed to work for me.
When get onto the boat in order to follow Hytham in the 'To Serve the Light' mission, he refuses to row, just stands there holding the oar. Please fix, i've tried everything to jumpstart him back into life. Thank you.
