Killer bug in the Shallows/Enemies in Nameless Pass

There is a bug in the shallows where, before I get to sacrament, almost every time I go to the far side to the northeast along the beach (in the alcove where you kick the ladder down from the bridge to the Risen fortress), if my character gets close to the dead end at the very end, near the last sand pile, he automatically dies for no apparent reason. Idk what this is about, because there are no enemies, and my character is fully equipped, but he immediately just dies for no reason.

There is another bug in which the sickle enemies in the nameless pass no longer jump down from their perches to engage with my character. I have to seek them out and climb to them to engage with them, whereas before they would jump down.
