Please, before adding a new leader/minister check the "***Tag Treasury & ID Allocation***" Thread, i put a complete list of the IDs where all the nation starts (for example, GER = 1) so you know where to start with your new IDs.
Every nation have 1000 IDs assigned, so if GER starts at 1 it uses until 1000, so the next nation starts at 1001.
Check the link:
***Tag Treasury & ID Allocation***
(the list are in the 3rd and 4th posts)
