The Green Badge award gives double the mining bonus on a newly conquered planet but only gives the regular population bonus.

If this is as intended, the description could be made more clear.

i.e.

Assimilation Locus
[ Planet Structure - Size:2, Mining:2, Population:200 ]
Puts the enemy to work in your mining facilities.
The mining bonus doubles if used on a 'New Colony' that you recently invaded. (limit 1 per planet)

Thank you. The description should have read 100 population base (200 after the bonus). This has been fixed.
