Fix from previous post turned out very inconsistent.
Even though the voidwalker quest is last taken, the bot randomly abandons wrong quest.
I tried out the following LUA code by @Droidz
It did NOT work, nothing happens. IF ANYONE KNOWS WHY THIS DOESNT WORK, PLEASE DO HELP !
I tried out following LUA code instead, I need to see how consistent it is. It might be perfect becouse I already have quests in Quest Log I dont want to abandon. :
