Playing 2.6.1 and I'm a newbie to Stellaris. Established a new colony now with 2 Pop but doesn't show under my Planets and Sectors Tab. Also both have the same governor. How watched a couple of YTubes for guidance but I am lost and just fumbling my way around trying to learn as I go.

1st, are you playing Steam or Gog? because the current Gog patch is 2.6.1.1 and you really do need that extra 20mb which gives you the extra 1

if you have Steam then 2.6.1 is correct
for Gog see the two images I posted for Galaxy 1 and Galaxy 2... if you don't have the extra 1 then your game is busted and you need the last patch to repair it



are you able to see the col started or are the people still on their ship?
see image for example of what they both look like
