Santa's watching, gotta keep fixing bugs! 

Fixes:

 Ambassadors get now correctly replaced when an already conquered Reign gets conquered by someone else
 Fixed NPCs in Dragon Queen's Terrace being recruitable on some occasions
 Fixed wonky positioning in Desert Princess' "Cinder Ribbon" scene
 Fixed rabbits sieging cat-controlled Moth Reign not showing sprites on the map
 Fixed wrong ambassador portrait in Bird's Reign
