Thx much for all the replies folks.
- No, there are no re-education centers on the planets I'm having problems with
- Its happened with many cultures
- I've gone beyond 4X (I'm referring to the ration of my influence to theirs on the assaulted planetary screen here...e.g: "IP=30(135)")
- I'm surprised about this "4x" rule, as most of my assaults will induce a "skull and crossbones" when my IP on the planet is still a fraction of theirs (e.g. assaulted planet IP's of "35(5)" will often have them in my games). Also most, other planets pop at much lower ratios (although these were assessed in the previous turn). Are you sure about this rule, and does it apply to DL Ver. 1.5?
- Finally, these non-popping planets are severe outliers: whereas the surrounding planets in the system will go pretty early in the assault, these (again, not special) planets will not go even when I have them under the influence of 12 fully loaded Influence bases (culturally and diplomatically maxxed out)...well well beyond where all the other planets revolted. Also, they display the Skulls early in the assault just like the surrounding planets (again...in my hands when their planetary IPs are are still much greater then my assaulting IPs), but just won't pop....so I finally give up.
Again...I really appreciate all the input, and thx.
