Engine ID from a pair engines get swapped when I do a read function. For instance, a Hudson is now a T-1. And T-1 is now Hudson. One of the engines (new T-1) is on the track, the other is not. Only way to fix it is to delete both engines and add them again.
It Just started after returning from York with both TIU and Handheld updated from 5.0 to 6.0 and the new engine . Affecting both handheld and Wifi. Could it be something with the new engine? This is strange.
