Finally I found a RV crash with a car in the town…but the frames are complete.
I remove the crap car part,and repaired the engine.But wheels reports lack.Now I have two 24" in the front of the RV ,four 25" under the RV body on line6 and line7,and I even add two 23" at the last of RV…It still report lack wheels.
Is it a bug? or I missed something?
BTW: I‘m use the #393 build with a new world.
