from what I understand this was not a major update so there is no need to redo the mods folder but the new ragehook and scripthook is not loading my mods folder. I'm not sure what to do about this.

I believe you still have to update the Update.RPF in your Mods folder. 

it still needs to be updated,  but you'll need to redo any visual mod and or weapons mods. if it doesnt update RPH loads OPen IV's plugin, and trys to draw the old data

I got same issue, I have updated update.rpf in mods folder, but somehow it just won't load within GTAV. No vehicle mods work, EUP won't start anymore

check  your vehicles.rpf....sonetimes the update removes them.....EUP needs to be reinstalled after updates

I had this problem aswell, for me it worked when I did a fresh install of mods folder. Delete mods folder, copypaste x64 and update folder from GTAV Directory, install vehicles fresh into new mods folder. Hopefully it is this easy for you too
