Ooo Icey found this very strange bug/glitch,
so all credit goes to him.
The bug is now fixed, so I guess we are about the only people in F2P who have these Members objects in our bank, while we've never been member on these accounts!
How it was done:
There is a Rotten log inside the Bandit Camp (far West of wilderness, about level 21), which members can pick to get 3 Fungi. F2P players could pick this log 1 time, to receive 3 Members objects.
Even after hours of waiting, and world hopping, the Fungi didn't spawn again, so the maximum number is 3.
