Birth of the Federation

Wasent sure how else to title this but i seem to have 2 issues with this game thats started in the last week, i am using the normal BOTF without mods, One, Whenever a minor race joins my empire all the food and industrial units disapear more of an annoying issue really but Two, i have noticed in the last few galaxies i have done there seems to be less and less star systems normally there`s over 90 of them now its barely 80 last one is 78, i use the same settings easch time,
They are in case you need to know.
Minor Races - Many

Randomn events - Off
Shape - Irregular
Size - Large

Is something going on or am i imagining it ?
Thanks Jack

issue 1. is a bug, but has a fix (note; fix is not 100% but much better than original code)
viewtopic.php?f=187&t=13#p33859
QD's patch name "Minors without Main Buildings System Takeover Bug (fix)"

issue 2. it is not your imagination, but galaxy generation is random so 20% change is to be expected.

I experienced #1 all the time back when I played vanilla via disk. I'm pretty sure the vanilla download has the fix already applied.
