Silver accounts can place anchors and items, Bronze accounts cannot place items unless they were placed during one of the very few (two I think, but its been so long) free Gold days that were given, like a 2 or 3 day Gold period (that did NOT make accounts from Bronze to Silver), I remember claiming my Red Skelly mercs and placing anchors on a few Bronze guys whom never had been Gold. Harashil is it possible those fresh f2p are on a Silver account? I have a few F2P accounts that have become Silver after getting max level nd buying a Krono for AA purposes, they lapse back to F2P but the account remains Silver and if I make a brand new level 1 character, they are silver and can place items in a guildhall.
Jet, sounds like an odd bug got your trader, very weird.
