X3 Crashed while setting up track/buss colors

I was playing with the track colors setting all the tracks to follow the buss color.
 
this is an existing project and I just used cntr-a to select all the tracks, hold down ctrl and click the track color then right click on the default and select follow buss. Then I changed the buss colors sometimes using the custom colors. I played around with different colors for a while and all was looking good until....
 
I tried to save the project and x3 crashed.
 
I sent off the crash dump and entered my email so I have a ticket.
 
I was not able to duplicate the crash when I reopened X3 I did the same things and saved the project successfully.
 
Just a heads up in case someone else sees this.
