Hungary - bug?

[maidros]

I am playing as Hungary, and I rivalled Poland, as Poland rivalled me. Fine, I got a larger army by hiring a bunch of mercenaries, which triggers the mission for Wallachia and Moldavia, which I accepted and completed. This gave me the mission `Weaken Poland'. I accepted this mission, which says I should conquer southern Poland - Ruthenia and Galitsa - region. Except, this mission falsely gets flagged as completed -I didn't own a single province in Ruthenia. I checked the mission conditions and it says I have to own Ruthenia before I get the mission to get a claim on the Polish throne. But it isn't working as stated. Immediately after Moldavia and Wallachia, the `Weaken Poland' mission flags as completed and I get the claim on the Polish throne. I wonder if this is a bug or a feature?

This is a feature. The mission Weaken Poland can be fulfilled in two ways: Either you own at least 9 provinces in Malopolska, Red Ruthenia(not the same as Ruthenia), or Sandomierz or you have a bigger army and more development(including subjects) than Poland/Commonwealth. You just fulfilled it in the second way

Thanks. That explains it.
