FFVI Pixel Remaster - Colossal 'Albrook Exit Tile' bug

When you get to World of Ruin, pay close attention to bugs that can happen. Save your game in many different save files because if any soft lock bug or that prevents you from continuing happens, an older save file can save you (in my case, something else saved me and I will explain below).
Yesterday this bug happened to me and I was very shocked, so I decided to record it to show you all:

-I was playing the game with Celes in Albrook, the first city you find in World of Ruin;
-For some reason when I left town, the game put me back in the World of Balance;
-It was a colossal bug, basically a soft lock bug;
-I couldn't go back and the Airship was on the other side of the world;
-I didn't realize that and ended up saving it by accident......
-Good thing...... I had used quick save before the fish hunt for Cid (a little after the World of Ruin started)
-This is like a separate save file (it's different from Autosave, from what I understand) without having to be at the save point;
-And, thank God, that saved me from a bug that could make me... restart the game.....
-However, I ended up going back just a little bit.

About the bug: one of the exit tiles from Albrook doesn't take you out of the city during World of Ruin, but back to World of Balance. I've been reading posts and it seems that this bug also happened in the Japanese version of FFVI (Super Nintendo) and it was fixed in the American one..... I wonder: how could they inherit this same bug in Pixel Remaster??

I was reading about other bugs and someone explained about a different situation with "Return to WoB from WoR" bug: a battle with the rat from Opera House if you didn't defeat all of them during the scene in World of Balance. I didn't get this bug (and I don't even want to get it) because I am still near Albrook in World of Ruin, so I would have some hours to arrive there again...
