Hey, I've been looking at the different ways you can upgrade your Gauss Cannons, and a couple things in the research tree I'm not sure contribute to their actual damage:
(see http://www.clansofsin.com/techtree/tec/2 for the online research trees)

Ferro-Uranite Rounds
increases damage for autocannon weapons
Advanced Ballistics
increases damage for autocannon weapons
Highly Conductive Rails
increases range for Gause cannons

Highly Conductive Rails requires the previous two skill researched first, but I dont think autocannon weapons are actually used by Gause Cannons. When i look at the .entity files they say the weapon of Gause cannons are Projectile and Gause type, meanwhile the autocannon weapon looks to be flak-like ships

so if this is the case, why would the game require researching an upgrade to autocannon weapons as a pre-req for the Gause cannon upgrade? or am i wrong, and Gause cannons actually do use autocannons?

Thanks!
