Sand Patch: Ac4400cw Ghost Livery?

Anyone else notice the ghost loco occasionally appear on AI trains?

I've seen it several times.

 

Seems to be a blank texture!
Did you happen to use the livery designer recently for the AC4400CW, and kept a livery there that you had been working on? Those custom liveries can actually appear in the timetable service mode as well! Otherwise, it could be a bug.

 

I've never used the livery designer, haven't had interest yet
