Sadly, minecraft isn't giving a crash .txt for me to attach here, but when putting vehicles(cars, planes, jets, military trucks) from these following mods, this message is given on chat: "Attempted to add (item from mod)(e.g.:iav:iav_seat_none) but that part doesn't exist in the pack item registry." I'm able to put them on the ground but right-clicking any of the vehicles that should be functioning just by right clicking works. Following mods are:

• ZDVehicles
• City Cars
• VEB Automobilwerke Schwikau
• R.A.G.E

And game crashes when trying to ride cars from Sphase Vehicles. I can enter them and briefly walk for like 2sec, but game crashes with no log of it. Any ideas on how should I proceed?

Closing due to seemingly fixed due to missing packs.
