Please explain your issue is in as much detail as possible.
The Northern Crusades of the Teutonic Order of the Holy Fury DLC get bogged down extremely fast and usually just stop occurring after one or two Crusades. This happens while there are still plenty of Pagan realms in the Baltic left. I haven't yet played a game with this game version in which more than three Northern Crusades took place! And because the Teutonic Order only take a handful of provinces, they remain weak and these provinces are retaken by the Pagans most of the time without the Teutons trying to re-conquer them.

Steps to reproduce the issue.
Start as a German Count or Duke in both the 1204 and 1220 start dates (but mostly the former), wait for the Teutonic Order to go north and join with any Northern Crusade they start. Keep playing for at least a century to see if they resume Northern Crusades after some time.

Also it should be noted that in most of my 1220 games the Teutonic Order never even moves north and usually just becomes a tributary of the Cumans.

Update: I've tried some Ironman games in earlier start dates (1066 start and the King's Crusade start) and had the same problem, with the Teutonic Order forming after the Crusades started but the Teutons stopping after a single Northern Crusade campaign. Same game version, only Music Mods in use.
