They have no way to prove you did not give them those items because you gave them access. You cannot just later say they took it...it is "he said, she said" scenario and they can't get involved with that. We limit our FC chest to one tab for anyone that just has basic items for new players and the other two are for our gardeners and crafters...just re do your set up and learn from this and hope it was not that much money. You did lock down your money right and they did not rob you blind on that too...right??
