I am unable to select an island group tile after it is placed on the map therefore I am unable to add villages, etc. Is this a known issue with Vassal 3.16.15 and CoP 1.4.2? Or. am I doing something wrong?
You have to hold down the Shift key to make the tiles selectable, then you can get at their right-click context menu. This is a configuration option when using the Does Not Stack trait, and if left undocumented in the module, users frequently get stymied.
