Never seen this Easter egg. Are you able to replicate the behavior with other files also?
Yes I can duplicate this with every pack and go file, I got paranoid right away....
Took a little bit till we got it figured out, like normal - Not a bug just some user input issues. I do Pack & Go probably a little different, in the search and replace dialog box I do one at a time, sometimes if you have a dash A or something like that it gets all of that same sequence and did screw up files.....
Since this was a "New" design and new assembly ect, I use either a work order number or a quote number to do the initial design and apply my correct part numbering in the Pack & Go later in the process. When I started this project I made last 4 numbers in my top and sub assemblies from 9000 to 9003 and I should have started my part numbers at -004 instead I made the mistake of going to -001...
So here is what happened Search File Number 86142-9001 - Replace with 4401KC-86142-001 again till I had all the 4 assemblies, then when I started doing the parts it was Search 86142-001 Replace with 4410KC-86142-004 and what happened it stacked up the "86142" number.
What I needed to do was Search for 86142- and Replace with ABC- and then I could continue like normal and it works, but it literally hours trying to figure it out, so yeah I can replicate it
Bottom line is this - Using Search & Replace, you can not have the same numbers in the same string ahead of the dash
This is what it looks like now
