AIW from Rfactor Track

[Raungale]

Hi, everyone,

I hope you can help me.
on some routes that I convert with the rfactortool, the aiw does not work properly. the cars drive jerkily left and right and completely lose track of the track. the wheels move very quickly left and right on the ai. does anyone know the problem. As I said, this is only the case on some routes. many thanks for your help
