You can try it - must work, but do backup of Native folder first. If will be some bugs - you still can do copy of Native folder, name that Native Flora Mod, for example, install mod to this folder and play single with this module. For multi - use original Native module.
Ok, thank you, what i have done is replaced the native stuff with the stuff that came in the new pack u gave me, i can go online with the better graphics and stuff, its awesome! Thank you, i dont get any bugs or anything.

But, on the campaign i have had 2 CTD'S so far, it is quite annoying, but its not too bad as long as i regularly save it so i don't lose any unsaved progress.
