So, I've played a game previously and conquered a dozen or so planets, but decided to start a new game when steam updated my copy and a bunch of mechanics and the gfx changed. Thought I'd start afresh to get to grips with the new things.
Anyhow, launched an invasion into an adjacent system with 8 lovely resource sites to get me started. Blasted through a few guard posts after the entry defences and then went straight for the orbital command and warp gate. Blew the gate and then the cmd. However just as I did, the planet exploded.
Yeah... that was kinda weird...
So I deploy my command center and realise it claims there is no supply 'since you are more than one hop from a planet you own' - which ironically, isn't true, since this is next door to my homeworld.
The map also suddenly shows the system offering 0 crystal or metal sites.
So, not to be deterred by randomly exploding planets, I withdraw my navy, build back to a healthy 500 man fleet, and set off to another planet adjacent to my homeworld. Rinse and repeat, we blast our way in, nail a few troublesome sites and then go for the orbital command, while a colony ship follows in with a guard force to protect the cmd construction. The fleet reaches the AI orbital cmd and does what comes naturally.
Then the planet exploded...
...
It really needs to stop doing that...
Thinking the steam update brought some new mechanic in I missed somewhere, I return to the tutorials. Run through the planet capture tutorial again, and it does sod all different to my own assaults just now.
So, what am I doing wrong?
