Hi
I think i tracked this bug or one close. Hard to reproduce
It occurs when you start a 'Long Campaign' and not a 'Generated campaign'
I used the default setting on my comp that was for some reason using UK as campaign nation in 1940.
Settings in prefs are set to 3000 points, and country training to off.
Choose Long Campaign.
You will in a normal way being offered 2975 points to buy your core.
If you exit at this point and try it again it will still be ok.
Now to the 'bug'...
Choose Long Campaign.
Use some of your 3000 points to buy something, or buy nothing (faster).
Click 'Done' and go to the support screen. Buy anything or nothing.
Change your mind and click 'EXIT'
Choose Long Campaign again.
This time you will usually be offered between 900 and 1100 points for your core.
Workaround : after you click on Long Campaign, click the 'Preferences' button and then exit on that screen. This will restore your 3000 core points until you use a support 'exit' again.
Seems you should get the thing right after a fresh start of the game anyway...
