when we were testing some of my models
maybe i know what the problem is
i replaced original games files with this one
and it came in with moddable version
i used the import collision on that old rome lvl, and maybe adrien did not modify the numA yet but later found out what it was for and made that assert in the c++ editor
be careful when you patch modded files, especially these ANCIENT ones
thats the thing i want to start from fresh game which is not modded at all
but i really dunno what to do
so i can make my own mods in piece
i most probably have some garbage left that i dont even know of
you should reinstall the game and make sure to keep track of your files and back them up
i dont have anything to be honest
i think the version i sent you has an autosave feature (which kind of works) maybe that can help you
