This mod likely wont be updated when 26.3 comes around, there is another mod that achieves the exact same thing right now

Open to LAN Fix

26.2 changed how Open to LAN worked by making you unable to use the Allow Commands button whilst in hardcore mode, and only applying that change to players that join via LAN.

This mod reverts this change so that you can Allow Commands in hardcore mode and forces the change to apply to the host as well.

Installation

Open to LAN fix works entirely client side. Only the player hosting the LAN world needs the mod.

For obvious reasons, this mod does not work for dedicated servers.
