I believe I hard locked myself by using the shears to get past the last gate in the forbidden forest maze before using them to get the sedative? The shears are no longer in my inventory and I still need a sedative plant.
you just gotta get the mug FILLED WITH BEER to the plant and click on it (with the mug) also idk if it was patched but you cant refill the mug if you gave it to the orc before putting the sedative plant into it.
