Problem:

No new kerbals seem to be spawning for me in the astronaut complex.  I've had a few client restarts and the game has advanced 18 years in total but I only have 4 kerbals hired.  5 assigned and Jeb  Bill and Bob available to be hired.

I don't think I have any mods that would interfere with  Kerbal creation.

I have created one Kerbal myself  "Bezoar Kerman" and modified one other kerbal in the save file by simply changing their name text and specialisation from tourist to scientist.

This isn't necessarily a problem because it's a science game and I don't mind creating the kerbals I need via the menu but it would be nice to have some available via the normal route if someone knows what I've done wrong and it can be fixed.

thanks in advance
