I hadn't even noticed that button was there, tbh... heh. I was controlling it from the civ/ind screen totally.
The behavior does seem to conform to design as per the recent posts.
@Vynadan:
I added CI to two planets via SM mode. It appears that the Convert CI options does not appear until you reselect "Installations" in the construction options list. Conversely, the Convert CI options remain when you select settlements without CI until you reselect Installations.
EDIT -
I had a 3000 km/s grav scout discover a Class III Black Hole. It had a displayed speed of 0 km/s. I ordered it to go back through the warp point and did a 5 second increment. The game gave an overflow error, and the scout immediately teleported to the center of the black hole, and has stayed there since. Oo

I was playing around with beam fighter designs when i noticed that my size 0.1 reactor had 3 times the neutronium cost of my size 0.5 reactor. It looks like there's a price/mineral inconsistency.
If I add the series 14 Gas-Cooled (0.1 size), it adds 0.25x Duranium 0.75x boronide 3x Neutronium and 1x build points to the design. The cost reported for the series 14 is 1. If I add the Series 52 Gas-Cooled (0.5 size), it adds 1.75x Duranium 5.25x Boronide 0.97x Neutronium and 7x build points to the design. The cost reported for the series 52 is 7. The neutronium isnt being taken to account in cost and is inconsistent across sizes. If I go into Design Tech the listed Neutronium use for all size of Gas-Cooled reactors is 16.2x and is similarly irrelevant to the cost.
