Is suggested that but, this no are creature or enemy guarding the treasuries yet. You must implement that first. Obviusly the team can approval that. Is the 9th in my list http://www.wildfiregames.com/forum/index.php?showtopic=15172 But nobody get an approval. So is not a defect, is a new feature put guardians and if treasure have guardians you can't grab the treasure until defeat them. You can try work with UnitAI file, or something similar.
