In an effort to correct a concern regarding sequential and predictable creature numbering, we introduced a new UIN generator which caused some older campaigns to fail to assign any UIN to a creature. This fix should address the 0 or null value of creatures. Additionally, it introduces a new element to the GM Context menu option under Alter->Team decision. The action can be applied to groups of creatures by drag selecting then right clicking to get to the context menu. Select Alter->Team and then in the decision pop-up check the Regenerate UIN check box. When this option is used, all selected creatures will have their UIN released and reassigned based on the Team they are assigned too. Party assignment is in the range of 1 to 99 All other team assignments are in the range of 100 - 999 Any other object on the map is assigned an ID in the range of 1000 - 999999 These ranges will be configurable in a future release!
