The game doesn't crash for me when I go game over. That is something unrelated to the mod. I've had that happen with vanilla FF7 though. No idea what causes it.
>2) I found bug in which despite collect an object from the ground this is regenerated to infinity
It just seems I can't fix this. I don't understand why, the code is all correct. sigh. I'll be removing that entirely for the next update.
. 3) the sword of cloud (now I can not remember the name, does not make me hit enemies ..... always miss ...)
The Buster Sword is not supposed to do that. Sounds like you're using old core files, which had a wrong flag ticked or you're using another gameplay mod on top.
.4) in the sewers of Midgar if you encounter an enemy "lobsters" Fighting goes to infinity (it seems that when it is their turn they do nothing).
Update the mod. Thats a problem present in the old core files, get the new ones from the thread.
5) If I talk to a guy in the slums of Midgar the conversation has never fine
also sounds like an old bug
I can only assume you're either using the slim flevel and / or old core files.
