When adding a Regional Template to a character the Region field does not update on the description tab until the character is saved, closed, and reopened. Could this have to do with the most recent change that blocked the field for editing via keyboard? This is primarily a problem when building a character that needs the region to qualify for a regional feat as they don't without an exit and re-enter.

In discussion in Andrew on the List Files Help group, it was decided that this "bug" likely extends to prevent editing of the REGION even by the program. That is, removing the template that assigned the region and adding another one changes the TEMPLATE in the character's .pcg file but does not update the REGION field. Updating it requires manual editing.
