Hue, if I'm right I've already updated it.
Does the development team have the capacity to ever implement the missing natives, or at least gracefully catch the cases when mods use this? I can image some authors not willing to update their (old) mods.
I've updated my mods (Manual Transmission & InversePower) to be compatible with CitizenFX.
Also yes, I know I'm using a mod with unsupported natives, I made it
Even talked to NTA about this but I still wonder if this could be worked around gracefully by the current FiveReborn team.
