I'm not sure if anyone else has had this but has anyone else using Trainz 12 had a little red bug come up in the screen and then find your train invisible? I had this problem before, found it was a script error in the couplers and also found a script error for the cab on all of my installed JR engines, with only a few exceptions. I even had three payware engines throw up the script error (BNSF 9-44CW, Conrail C40-8, and UP SW1500. After I fixed the issue with the couplers the C40-8 showed a script error with the cab. Has anyone been able to fix this error so it doesn't show up again?? If you need additional info, see my previous thread entitled 'Script Exceptions in TS12'.
