Lua Error Chassis

I get this error when I hover over the ‘semi-space frame’ chassis option but it only happens with one specific car.

Exception: Lua Function Call: ValidateAll ValidateAll: scripts/shared/functional/COMMON/CCarCalculator_Chassis.lua:456: attempt to index a nil value

I have found that if I make a car that the model year won’t have the Semi-Space Frame available, but then make the trim level high enough for it to be unlocked, it will show up but won’t be able to be used. Same thing happens with Pushrod Suspension.
