I did that intentionally because the last 25 or so slots had data in some of the columns. If you are certain those slots are fair game for us to edit and that data was refuge, then I can easily extend the range to 9999.
I just checked manual again Allied slots rang from 3000 to 9999
I have created russian ships in the range 9818 to 9997 these now apprear in game and are working ok so the last 25 slots are ok to use
Which scenarios are resulting in the ships being shifted a slot?
sen 155 CHS 1.02 and sen 158 which is beening built off 155
I have e-mailed sen 155 and 158 to you for testing( they wont work in game just as a Sen you need all of the CHS package but will be ok for testing in Excel)
