In my game Venice backed out and Hungary hasn't guaranteed Albania... but Bohema allied Albania. In the end, it couldn't save them. What I find disturbing are some weird alliances right at the start of the game:
Ottomans - Novgorod (Muscovy isn't a rival of Ottos)
Qara Qoyunlu - Georgia (allied heretic neighbors)
Albania - Bohemia (there's literally zero strategic reason for Bohemia do ally Albania)
