Well a unique consolation, nice gesture but shouldn't everyone who was in the game at the time be similarly entitled? Whether or not affected by a bug, suddenly its become very good luck if TS makes a mistake (for some people).
People are now bidding millions to obtain this rare item.
And the fibres which are being dropped by the dust bunnies, imply by their description might be useful.
Certainly that item will be in very limited supply, and unobtainable unless purchased from the lucky stickholders.
I think its a terrible error. Akin to Jagex making the party hats and similar holdiay items tradeable. Such items became the most coveted and valuable items in the Runescape world, to the regret of Jagex.
