Just encountered a bug I didnt see reported yet (or missed it)
Survey crew found +15 malevolent
With previus events i got:
+10 Benevolent
+15 Pragmatic
+25 Malevolent
Culture standings on all is 0%
Now the turn butting has 'Ideology' and i get to pick one.
So i skip between ideologies to select the one i like most. For this game i wanted Pragmatic, so i navigate from Malevolance to Pragmatism.
At that point the 'unlock' button disables.
After selecting done, reopening Ideology the pragmatism is selected and the unluck button enabled.
Edit: On selecting unlock however it did unlock Malevolance
