I can confirm that I was able to progress past the Nobunaga battle cutscene in a playthrough where I did not activate the trainer at any time.
Nothing to do with trainer, i did crash on the stray dogs on my first run, did load up earlier save and changed what ever i could, did run without trainer and crashed no matter what i did, then i did read on comments on youtube video that favor YAYA and please her when doing prev quest and she is there. So i did start up a 2nd run and did what they told and bam she is at my home working for me, The Horsemen quest did have same issue related to yaya and even that one went smooth. i still have the first startup saves and will test it again when i get the time, only issue is i need to get back to before i meet Yaya the first time to answer "correct". And yes i did use trainer the 2nd time also so for sure it is game issue and not trainer. And if people read read me files and take warnings from caliber u dont crash with it. Just saying!!
No one tells you that
they didn't use a trainer!
so why is it that the first time i crash on the stray dogs but not the 2nd time there with same setup, and ofc same use of trainer? Why are u even here? u always blame ch trainers.
