Iconian tech values - version 1.2 - are these incorrect?

Hi,

I've been working my way gently through the races not at a v high level (genius) and just started playing the Iconians under version 1.2

After the opening, I've currently got  177 research/turn (as it stands - obviously I could play with the planets to optimise this) and these values in the tech tree:

Under Engineering

Interstellar Logistics 6 turns

but Zero Gravity Construction 16

Under warfare

Pulse cannons 10

but Matter Disruption 20

I was wondering whether these two, Zero Gravity Construction and  Matter Disruption are due to multipliers due to the specific race or some sort of input error.

I see that ZGC seems to have the same base research cost of 512 in the other tech trees but remember it as being a lot easier to research than 16 turns.

Many thanks,

Jon
