Essentially, yeah, as someone who was around since Part 1 and can remember those comments well, these complaints are nothing but hilarious really XD The truth of the matter if that nobody will ever be fully happy with what Fujino does because he does SO many things he's bound to hit stuff you dislike sooner or later as much as he's of doing something you do like
It may not be this one but we MAY get one more before the game ends?? The thing about battle updates is that for Fujino they also probably lost a lot of power because Inoda can now all but openly fuck Asuna whenever he wants, he doesn't need to take advantage of a fighting situation to fool around with her anymore when he can just ask her to come over to fuck and she's all but certainly gonna say yes in and out of the game. So between that and the issues he mentioned last time, is no wonder he may not do more again.
And I actually give it a 50/50 of it being Yui as it could be something from the game, given how much fuckery can still happen in FoG to be honest (We know from Part 1 that weird 'glitches' like a player being kidnapped and left at the mercy of someone to rape can happen just because they're part of a quest lol). It can even be a hybrid of both, like, remember, Yui just wanted to spend time with Inoda, she didn't know the reward for the quest they were doing as an item that turned someone into a succubus, nor was she actively planning on Inoda to end up using it on Liz while fucking her stupid, that just happened as a coincidence of her trying to let him escape her by giving him a buff to his potion while they were wearing the master/slave reversible stuff. So I can totally imagine it could be Yui taking them to a quest in a forbidden zone removed from the game and then trying to get Inoda and Asuna some alone time, without knowing that part of the quest involved turning Asuna into a cow girl to milk her, it's just Inoda's luck at work again XD
