This probably started with the last patch to main branch. Like title says, you get your normal XP reward on discovering the parasang containing a staircase to lair or workshop. But then, on going down the stairs, you get the same XP amount, again! I feel silly to complain about it but thought ya'll might wanna know. As an example, in today's daily a quest giver sent me to a gunsmith, and I got 1350 xp, twice, for checking it out.
