DHQ Quest Problem

[Zantera.S]

Hey guys so I went to test a few quests and stuff before opening my server and when I went to do DHQ and claim my rewards it would actually let me open the chest and take the items instead of it giving it to me in my backpack. By doing this only one person could take the reward because it isn't working properly.

This is the error I got

[18/5/2013 9:40:58] [Error - Action Interface]

	doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, result)

Any help is greatly appreciated
