I got a bug report for the community league mod, where a player was not able to progress the hidden path quest.
They progressed it to the point in normal where they had the three runestones, did not go to the temple, instead carried them over to ultimate to complete the quest and get skill point rewards for all difficulties. However, the quest would not progress past this point:
This turned out to be due to the player having extra copies of the runestone in their stash, while the quest file is requiring them to have exactly one.
I’ve checked in a different, more basic mod and multiple of the same runestone could be placed in the personal stash.
This to me appears as an unintended interaction when the shrines / blacksmiths were changed to consume items from the stash.
Let me know if any other information is needed.
