Thanks for the heads up @Skeptical_Bunny, it has been so much time ever since I don't even try to do anything with more than one character simultaneously if they are chained, to the point that I forgot how exactly the chained party works when you change the active character. I fixed my thread's title and added some other stuff that I noticed as I played the game today, I definitely appreciate your post.
This issue is quite annoying and I might in fact just take a few weeks away from the game just to make sure that I can experience something closer to what I played a couple months ago, when I finalized my 2nd Tactician playthrough and moved onto other games, since I have at most only a few hours to play games and then I have to do other stuff.
