Hi Mike;
After doing a lot of testing I have been able to resolve the issue.
Here is the setup:
I did a full clean install of RW3.
Using RWtools (latest version) and using the TestTrak route, I cloned the Free Roam: UK Stock scenario.
Using the cloned Free Roam: UK scenario I updated the Class 47 consist from BR Blue Class 47 to ES44AC UP Heritage, Class consist 55 to ES44AC BNSF and Class 37 consist to ES44AC UP...saved and clear RW3 cache.
Ran the updated cloned scenario...check the three units and all looked and worked correctly. I the reedited the three consists in the cloned scenario changed the same units to different consists (on different tracks....saved and cleared cache.
Ran the updated cloned scenario a second time with the units on different track and all looking correct......so far, so good.
Now using NS GE AC4400CW-7506.zip file, which has been updated for TS2012 lights (from Digital Forum:
http://s1.zetaboards.com/DigiRails_Forums/index/) installed the new NS ES44AC 7506 (this has a static number), edited the cloned scenario class 55 consist with the new locomotive...saved and cleared cache.
Ran the updated scenario and the new NS ES33AC 7506 shows up fine, but the auto-number from the previous locomotive is on top of the static number. The NS ES44AC has no .dcsv file and the digits.bin file in its engine\texture file is pointing to the correct directory. Okay, problem recreated. No matter from this going forward using the cloned scenario can I make it go away.
So I created a new clone of the original Free Roam: UK Stock. Now using the new clone I updated the Class 47 and Class 37 consists to ES$$AC Heritage and UP respectively. The Class 55 this time I updated to NS ES44AC 7506...saved and cleared cache.
Ran the scenario and all displayed correctly...the NS ES44AC 7506 had no auto-numbers showing (as it should be). If I updated the new cloned scenario with Class 55 consist changed to ES44AC BNSF...saved and cleared cache....run the scenario and all the units show correctly.
Now if I update the new cloned scenario again class 55 consist back to NS ES44AC 7506...save and clear cache....then run the new clone scenario all tree display, but the NS ES44AC 7506 now has the BNSF auto-number showing over the static number.
So, my conclusion is that it has a combination of the scenario and older RW2 units not working well with each other. It is like the scenario is storing the unit auto-numbers so if you do a continuation it will use the same numbers on the units. However if you start over using new units the older RW2 units are not resetting the auto-number and picking up the previous auto-number. However, if you start with a clean (new) cloned scenario and update once with the units (including RW2 type) then it works fine.
It would be nice to have someone else replicate my test and see if one is seeing the same results as I being I am still learning how the sim. works and the impact of the latest updated application changes.
