As far as I can tell, this .dll has only been changed a week ago. While that might be a long time to you, to guys trying to make it work, in their free time it isn't.
Only two days ago or something, the LSPDFR guys released their patch to combat these changes and while I am not sure if this new update from them has a fix for online yet, I do know that in terms of the bigger picture the week we have had, is nothing.
You must be patient, updates will come and they will mess up modding for a few days but generally, as proven by LSPDFR and their speedy response, nothing is ever permanent.
Yeah, but that rage plugin from the LSPDFR seems to be quite different from what OPEN IV uses. Also sometimes R* does a pretty good job at patching stuff. I don't know but I'm hoping they figure it out.
