Quest completed not saved due to lost connection to the internet?

Yesterday evening I completed “Fight for Zhongdu” quest before leaving the game. Today I open the game and notice I’m still in the same quest (60% of the quest done). I remember I’ve lost connection to the wifi while mid quest and I’ve only reconnected after finishing it (while already in the starting menu), this might have some connection to what I’m experiencing right now. I don’t mind completing it again, only wanted to raise awareness.
