Where: (where is the bug): Padisah quest
What: (what happened):
how to do
1. Accept quest from padisah for trade deal
2.go to John farm to offer trade deal and collect slave neckle.
3.then go to napoleon, quest mark may not appear but player can still trigger quest by double tap npc.
4. Back to padisah he will give you item for napoleon
5. then talk to napoleon and later to padishah (get reward)
6.Complete quest for john farm and then talk to padisah you get reward but xp only.
Why: (Why do you think tis is a bug): normaly you choose one of npc only to finish quest. by doing this plaher can have double reward that supposedly not, and this not fair for player that only complete one of it.
Other comments: (add any other information you think is relevant): this bug was encounter on 3.9 early day bug there chance this has already being here but no one report it/do it because small reward and profit gain from it.
