I met a husk near the end with 60 hp i killed. Didnt see its name but 60 hp confirmed that it must have been the pharaoh. i didnt recieve a pharaoh head and the fatigue never disapeared. when i entered the boss room there was no pharaoh only ordinary "husk guards". is there any way for me to disable the fatigue in this temple only?

I have a similar issue. I think what happened with mine was that I killed a bunch of the guardian husks first, and I saw the pharaoh put on helmet one of them dropped. Then, when I killed the pharaoh, the temple kept the fatigue. I was able to replicate this in creative by going to a temple, dropping a netherite helmet for the pharaoh to pick up, then switching to survival and killing it. Is the check to disable the fatigue based on killing a husk specifically with the pharaoh mask on? Would it be possible to prevent the pharaoh from picking up helmets if there's no other way to create the end flag for the mining fatigue debuff? Alternatively, having the guardian husks not wear/drop headwear would probably remove 99% of the situations where this can happen.
