This is understandable, but the problem is that Johan(Mughals) is basically giving the game away to Yonaz(Bahmanis). And nobody is trying to stop it.
We don't know the relationship between the two at the office heh
The Mughals have not had the power to take out Bahamanis ever, Ming at the start was AI. The Ottos were on the far side of him, allied with everyone, and the Mamluks also bordered him and the Ottos would want revenge and the Russians had already been attacked by them in the past. It was an evolving story and you are missing the context.
