ServiceStartYear issue

[UllyB 1,207]

I wanted to change a ServiceStartYear of a plane from 1984 to 1991. I modified the data.ini aircraft plane entry accordingly but the start year in Single missions it's still ...1984. I thought of the reasons why but I don't see what I miss. The option.ini is set from 1960 to 2050 so there , there is no problem. I know that for data changing there are no other files involved except option.ini and aircraft data.ini entry file. Why can't I change that date and how can I change it please ? Thank you.

 

PS - I checked the KB for this issue and there is no answer there.

I discovered why. The plane had an export date smaller then the new service day entry data....

 

Sorry.
