Problem with Disappearing Wheels when making a Train, Please Help

Ok so I'm making a train and 3 wheels in front are missing. 2 on the front left side and 1 on the right side.

 

I literally have tried everything I know, There is no alpha mask, there is no flipped normals. I even flipped the normal to the wrong direction to see if that would work and it doesn't. I tried reset x form. I looked at the UVW Map lines to see if anything was wrong or outside the map space. Nothing.

 

So I tried replacing them with the wheels on the front that work and they still just disappear. I even removed all the front wheels and then replaced them with all the back working wheels and then the same wheels that are missing stay missing.

 

I tested it out in game to see if it would work anyways and the wheels end up spinning on a huge loop bigger than the train. Im not sure why either.

 

Tried restarting game, restarting computer. Nothing is working. Please help me figure this out. Thanks

 

I'm really starting to think there is a serious bug with the asset editor.... I just tried out an older working model that I know worked for a fact and even that is not working correctly. Even when I place new wheels in any of that missing wheels area they just keep disappearing.

 

I just remodeled the wheel completely deleted every single old wheel I had and now the disappearing wheels are on the back side of the train now. How does that make any sense at all?

 

New Update... I just decided to start a whole new max file, Just made some cylinders, didnt even bother to uv map them. Did collapse all and reset xform and exported the fbx. I still get this missing wheel error happening. It has to be the editor some how, because it was working perfectly fine before...

 

 

Here it is in Max...
