I know, its probably a bug, but I couldnt find where to report bugs around here, so if any moderator thinks this thread is inappropriate here, plz feel free to move or close it.
Still, its annoying, I need a sup WS rune and its the only rune which somehow isnt available at the rune trader, look:
Idea: Sup rune of Wilderness Survival at Rune Trader
Reinfire
Vinraith
They're probably sold out at the moment.
Arkantos
It's just sold out. All the NPC traders get their items from players. So if theres a high demand and low supply, the item may go sold out.
