Hello Sega Chief!
Yesterday I bought FFVII on steam just to try your mod! Once I've played too much of this game on my old PS1, your mod looks so amazing that motivated me to play it again (it's been a loooooong time since I last played).
Thing is... I liked it very much until get stuck in this bug...
After plasma buster, when Cloud falls in church and find Aeris, she asks for help when Reno arrives. When the screen changes and you must go further into the church, Aeris starts to take care of flowers again and two "teleporting" kids shows up from nowhere. If I go towards Renno, Aeris (tending the flowers) disappears and a lot of blue soldiers appear in her place. I can even get out the church through the front door...
Reload before the fight with plasma buster doesn't help. I'm using just NT 1.4 (3rd October 2016) on a fresh install of steam version of the game.
Sorry about my english, not native speaker
