Not really Mandea, its all random. On my latest game i found all 3 in village in verona

Troups rare for me - Where i find pirates ?
 

Is bad to be random troups.
I wonder when, and if... i find pirates.

Sure it can be annoying but i wouldnt say it's bad, it adds some charm to the game imo. ;) You could also use the savegamescanner to be sure as someone mentioned earlier.

OK. What is savegamescanner ? :))
...and where i find it ? :)
